If a spell or activated ability has a mana cost, alternative cost, additional cost, and/or activation cost with an {X}, [-X], or X in it, and the value of X isn’t defined by the text of that spell or ability, the controller of that spell or ability chooses and announces the value of X as part of casting the spell or activating the ability. (See rule 601, “Casting Spells.”) While a spell is on the stack, any X in its mana cost or in any alternative cost or additional cost it has equals the announced value. While an activated ability is on the stack, any X in its activation cost equals the announced value.

If a player is casting a spell that has an {X} in its mana cost, the value of X isn’t defined by the text of that spell, and an effect lets that player cast that spell while paying neither its mana cost nor an alternative cost that includes X, then the only legal choice for X is 0. This doesn’t apply to effects that only reduce a cost, even if they reduce it to zero. See rule 601, “Casting Spells.”

A spell is a card on the stack. As the first step of being cast (see rule 601, “Casting Spells”), the card becomes a spell and is moved to the top of the stack from the zone it was in, which is usually its owner’s hand. (See rule 405, “Stack.”) A spell remains on the stack as a spell until it resolves (see rule 608, “Resolving Spells and Abilities”), is countered (see rule 701.6), or otherwise leaves the stack. For more information, see section 6, “Spells, Abilities, and Effects.”

An instant or sorcery spell is targeted if its spell ability identifies something it will affect by using the phrase “target [something],” where the “something” is a phrase that describes an object and/or player. The target(s) are chosen as the spell is cast; see rule 601.2c. (If an activated or triggered ability of an instant or sorcery uses the word target, that ability is targeted, but the spell is not.)

Aura spells are always targeted. An Aura’s target is specified by its enchant keyword ability (see rule 702.5, “Enchant”). The target is chosen as the spell is cast; see rule 601.2c. An Aura permanent doesn’t target anything; only the spell is targeted. (An activated or triggered ability of an Aura permanent can also be targeted.)

If a cost includes a mana payment, the player paying the cost has a chance to activate mana abilities. Paying the cost to cast a spell or activate an activated ability follows the steps in rules 601.2f–h.

If a cost is reduced by an amount of mana represented by a hybrid mana symbol, the player paying that cost chooses one half of that symbol at the time the cost reduction is applied (see rule 601.2f). If a colored half is chosen, the cost is reduced by one mana of that color. If a generic half is chosen, the cost is reduced by an amount of generic mana equal to that half’s number.

Any number of additional costs may be applied to a spell as it’s being cast or to an ability as it’s being activated. The controller of the spell or ability announces their intentions to pay any or all of those costs as described in rule 601.2b.

Only one alternative cost can be applied to any one spell as it’s being cast. The controller of the spell announces their intentions to pay that cost as described in rule 601.2b.

If an alternative cost is being paid to cast a spell, any additional costs, cost increases, and cost reductions that affect that spell are applied to that alternative cost. (See rule 601.2f.)

If the mana cost of a spell or the activation cost of an activated ability contains a mana symbol that can be paid in multiple ways, the choice of how to pay for that symbol is made as its controller proposes that spell or ability (see rule 601.2b).

If a spell or ability causes a card to be drawn while another spell is being cast, the drawn card is kept face down until that spell becomes cast (see rule 601.2i) or until the casting process is reversed (see rule 732, “Handling Illegal Actions”). The same is true with relation to another ability being activated. If an effect allows or instructs a player to reveal the card as it’s being drawn, it’s revealed after the spell becomes cast or the ability becomes activated. While face down, the drawn card is considered to have no characteristics and can’t be used to pay any part of the cost of the spell or ability that would require the card to have specific characteristics.

Any additional cost listed in an object’s rules text or imposed by an effect isn’t part of the mana cost. (See rule 601, “Casting Spells.”) Such costs are paid at the same time as the spell’s other costs.

A player who has priority may cast an artifact card from their hand during a main phase of their turn when the stack is empty. Casting an artifact as a spell uses the stack. (See rule 601, “Casting Spells.”)

A player who has priority may cast a creature card from their hand during a main phase of their turn when the stack is empty. Casting a creature as a spell uses the stack. (See rule 601, “Casting Spells.”)

A player who has priority may cast an enchantment card from their hand during a main phase of their turn when the stack is empty. Casting an enchantment as a spell uses the stack. (See rule 601, “Casting Spells.”)

A player who has priority may cast an instant card from their hand. Casting an instant as a spell uses the stack. (See rule 601, “Casting Spells.”)

A player who has priority may cast a planeswalker card from their hand during a main phase of their turn when the stack is empty. Casting a planeswalker as a spell uses the stack. (See rule 601, “Casting Spells.”)

A player who has priority may cast a sorcery card from their hand during a main phase of their turn when the stack is empty. Casting a sorcery as a spell uses the stack. (See rule 601, “Casting Spells.”)

A player who has priority may cast a battle card from their hand during a main phase of their turn when the stack is empty. Casting a battle as a spell uses the stack. (See rule 601, “Casting Spells.”)

Some effects tell a player to play with the top card of their library revealed, or say that a player may look at the top card of their library. If the top card of the player’s library changes while a spell is being cast, the new top card won’t be revealed and can’t be looked at until the spell becomes cast (see rule 601.2i). The same is true with relation to an ability being activated. If the top card of the player’s library changes while a player is taking a special action (see rule 116, “Special Actions”), the new card won’t be revealed and can’t be looked at until the player has finished taking that special action.

When a spell is cast, the physical card is put on the stack (see rule 601.2a). When an ability is activated or triggers, it goes on top of the stack without any card associated with it (see rules 602.2a and 603.3).

A card exiled face down has no characteristics, but the spell or ability that exiled it may allow it to be played from exile. Unless that card is being cast face down (see rule 708.4), the card is turned face up just before the player announces that they are playing the card (see rule 601.2).

Face-down cards in exile should be kept in separate piles based on when they were exiled and how they were exiled. If a player is instructed to choose an exiled card, the player may choose a specific face-down card only if the player is allowed to look at that card. Otherwise, they may choose a pile of face-down exiled cards, and then a card is chosen at random from within that pile. If choosing such a card is part of casting a spell or activating an ability, the chosen card isn’t revealed until after that cost is fully paid. (See rule 601.2i.)

Previously, the action of casting a spell, or casting a card as a spell, was referred to on cards as “playing” that spell or that card. Cards that were printed with that text have received errata in the Oracle card reference so they now refer to “casting” that spell or that card.

Some effects still refer to “playing” a card. “Playing a card” means playing that card as a land or casting that card as a spell, whichever is appropriate.

To cast a spell is to take it from where it is (usually the hand), put it on the stack, and pay its costs, so that it will eventually resolve and have its effect. Casting a spell includes proposal of the spell (rules 601.2a–d) and determination and payment of costs (rules 601.2f–h). To cast a spell, a player follows the steps listed below, in order. A player must be legally allowed to cast the spell to begin this process (see rule 601.3). If a player is unable to comply with the requirements of a step listed below while performing that step, the casting of the spell is illegal; the game returns to the moment before the casting of that spell was proposed (see rule 732, “Handling Illegal Actions”).

To propose the casting of a spell, a player first moves that card (or that copy of a card) from where it is to the stack. It becomes the topmost object on the stack. It has all the characteristics of the card (or the copy of a card) associated with it, and that player becomes its controller. Any continuous effects that modify the characteristics of the spell as you start casting it begin as it is put on the stack (see rule 611.2f). Any one-shot effects that cause the spell to gain abilities as you cast it apply as it is put on the stack (see rule 610.5). The spell remains on the stack until it resolves, it’s countered, or a rule or effect moves it elsewhere.

If the spell is modal, the player announces the mode choice (see rule 700.2). If the player wishes to splice any cards onto the spell (see rule 702.47), they reveal those cards in their hand. If the spell has alternative or additional costs that will be paid as it’s being cast such as buyback or kicker costs (see rules 118.8 and 118.9), the player announces their intentions to pay any or all of those costs (see rule 601.2f). A player can’t apply two alternative methods of casting or two alternative costs to a single spell. If the spell has a variable cost that will be paid as it’s being cast (such as an {X} in its mana cost; see rule 107.3), the player announces the value of that variable. If the value of that variable is defined in the text of the spell by a choice that player would make later in the announcement or resolution of the spell, that player makes that choice at this time instead of that later time. If a cost that will be paid as the spell is being cast includes hybrid mana symbols, the player announces the nonhybrid equivalent cost they intend to pay. If a cost that will be paid as the spell is being cast includes Phyrexian mana symbols, the player announces whether they intend to pay 2 life or a corresponding colored mana cost for each of those symbols. Previously made choices (such as choosing to cast a spell with flashback from a graveyard or choosing to cast a creature with morph face down) may restrict the player’s options when making these choices.

The player announces their choice of an appropriate object or player for each target the spell requires. A spell may require some targets only if an alternative or additional cost (such as a kicker cost) or a particular mode was chosen for it; otherwise, the spell is cast as though it did not require those targets. Similarly, a spell may require alternative targets only if an alternative or additional cost was chosen for it. If the spell has a variable number of targets, the player announces how many targets they will choose before they announce those targets. In some cases, the number of targets will be defined by the spell’s text. Once the number of targets the spell has is determined, that number doesn’t change, even if the information used to determine the number of targets does. The same target can’t be chosen multiple times for any one instance of the word “target” on the spell. However, if the spell uses the word “target” in multiple places, the same object or player can be chosen once for each instance of the word “target” (as long as it fits the targeting criteria). If any effects say that an object or player must be chosen as a target, the player chooses targets so that they obey the maximum possible number of such effects without violating any rules or effects that say that an object or player can’t be chosen as a target. The chosen objects and/or players each become a target of that spell. (Any abilities that trigger when those objects and/or players become the target of a spell trigger at this point; they’ll wait to be put on the stack until the spell has finished being cast.)

If the spell requires the player to divide or distribute an effect (such as damage or counters) among one or more targets, the player announces the division. Each of these targets must receive at least one of whatever is being divided.

The game checks to see if the proposed spell can legally be cast. If the proposed spell is illegal, the game returns to the moment before the casting of that spell was proposed (see rule 732, “Handling Illegal Actions”).

The player determines the total cost of the spell. Usually this is just the mana cost. Some spells have additional or alternative costs. Some effects may increase or reduce the cost to pay, or may provide other alternative costs. Costs may include paying mana, tapping permanents, sacrificing permanents, discarding cards, and so on. The total cost is the mana cost or alternative cost (as determined in rule 601.2b), plus all additional costs and cost increases, and minus all cost reductions. If multiple cost reductions apply, the player may apply them in any order. If the mana component of the total cost is reduced to nothing by cost reduction effects, it is considered to be {0}. It can’t be reduced to less than {0}. Once the total cost is determined, any effects that directly affect the total cost are applied. Then the resulting total cost becomes “locked in.” If effects would change the total cost after this time, they have no effect.

If the total cost includes a mana payment, the player then has a chance to activate mana abilities (see rule 605, “Mana Abilities”). Mana abilities must be activated before costs are paid.

The player pays the total cost. First, they pay all costs that don’t involve random elements or moving objects from the library to a public zone, in any order. Then they pay all remaining costs in any order. Partial payments are not allowed. Unpayable costs can’t be paid.

Once the steps described in 601.2a–h are completed, effects that modify the characteristics of the spell as it’s cast are applied, then the spell becomes cast. Any abilities that trigger when a spell is cast or put onto the stack trigger at this time. If the spell’s controller had priority before casting it, they get priority.

A player can begin to cast a spell only if a rule or effect allows that player to cast it and no rule or effect prohibits that player from casting it.

If an effect prohibits a player from casting a spell with certain qualities, that player may consider any choices to be made during that spell’s proposal that may cause those qualities to change. If any such choices could cause that effect to no longer prohibit that player from casting that spell, the player may begin to cast the spell, ignoring the effect.

If an effect allows a player to cast a spell with certain qualities as though it had flash, that player may consider any choices to be made during that spell’s proposal that may cause that spell’s qualities to change. If any such choices could cause that effect to apply, that player may begin to cast that spell as though it had flash.

If an effect allows a player to cast a spell as though it had flash only if an alternative or additional cost is paid, that player may begin to cast that spell as though it had flash.

If a spell would have flash only if certain conditions are met, its controller may begin to cast that spell as though it had flash if those conditions are met.

Some rules and effects state that an alternative set of characteristics or a subset of characteristics are considered to determine if a card or copy of a card is legal to cast. These alternative characteristics replace the object’s characteristics for this determination. Continuous effects that would apply to that object once it has those characteristics are also considered.

Some effects allow a player to cast a spell with certain qualities from among face-down cards in exile. A player may begin to cast such a spell only if they can look at the face-down card in exile.

While announcing the choices of any modes, alternative costs, and/or additional costs as described in rule 601.2b, some options may be available to a player only if other choices are made that would normally be made later in that rule’s instructions. In that case, the spell’s controller may consider any other choices to be made in that step. If any such choices could allow them to choose a particular mode, alternative cost, or additional cost, they may do so.

If a player is no longer allowed to cast a spell after completing its proposal (see rules 601.2a–d), the casting of the spell is illegal and the game returns to the moment before the casting of that spell was proposed (see rule 732, “Handling Illegal Actions”). It doesn’t matter if a rule or effect would make the casting of the spell illegal while determining and paying that spell’s costs (see rules 601.2f–h) or any time after the spell has been cast.

Once a player has begun casting a spell that had flash because certain conditions were met or that could be cast as though it had flash because certain conditions were met (see 601.3d), they may continue to cast that spell as though it had flash even if those conditions stop being met.

Some spells specify that one of their controller’s opponents does something the controller would normally do while it’s being cast, such as choose a mode or choose targets. In these cases, the opponent does so when the spell’s controller normally would do so.

If there is more than one opponent who could make such a choice, the spell’s controller decides which of those opponents will make the choice.

If the spell instructs its controller and another player to do something at the same time as the spell is being cast, the spell’s controller goes first, then the other player. This is an exception to rule 101.4.

Casting a spell that alters costs won’t affect spells and abilities that are already on the stack.

If a spell or ability that refers to the “activation cost” of an ability modifies how a player may pay that cost, that modification applies to the total cost of that ability, even if that cost is increased and/or decreased by other effects. See rules 602.2b and 601.2f.

The remainder of the process for activating an ability is identical to the process for casting a spell listed in rules 601.2b–i. Those rules apply to activating an ability just as they apply to casting a spell. An activated ability’s analog to a spell’s mana cost (as referenced in rule 601.2f) is its activation cost.

The remainder of the process for putting a triggered ability on the stack is identical to the process for casting a spell listed in rules 601.2c–d. If a choice is required when the triggered ability goes on the stack but no legal choices can be made for it, or if a rule or a continuous effect otherwise makes the ability illegal, the ability is simply removed from the stack.

If an object has an ability printed on it that causes a player to pay a variable additional cost as it’s cast and an ability printed on it that refers to the cost paid “as [this object] was cast,” these abilities are linked. The second refers only to the value chosen for the cost listed in the first as the object was cast as a spell. See rule 601.2b.

If an effect of a spell or ability offers any choices other than choices already made as part of casting the spell, activating the ability, or otherwise putting the spell or ability on the stack, the player announces these while applying the effect. The player can’t choose an option that’s illegal or impossible, with the exception that having a library with no cards in it doesn’t make drawing a card an impossible action (see rule 121.3). If an effect divides or distributes something, such as damage or counters, as a player chooses among any number of untargeted players and/or objects, the player chooses the amount and division such that each chosen player or object receives at least one of whatever is being divided. (Note that if an effect divides or distributes something, such as damage or counters, as a player chooses among some number of target objects and/or players, the amount and division were determined as the spell or ability was put onto the stack rather than at this time; see rule 601.2d.)

If an effect gives a player the option to pay mana, they may activate mana abilities before taking that action. If an effect specifically instructs or allows a player to cast a spell during resolution, they do so by following the steps in rules 601.2a–i, except no player receives priority after it’s cast. That spell becomes the topmost object on the stack, and the currently resolving spell or ability continues to resolve, which may include casting other spells this way. No other spells can normally be cast and no other abilities can normally be activated during resolution.

Some static abilities create one-shot effects that cause spells a player casts to gain an ability as that player casts them. These effects begin to apply to appropriate spells at the time the player puts such a spell on the stack. See rule 601.2a.

Some spells and abilities generate a continuous effect that modifies the characteristics of the next spell a player casts, the next spell that fulfills certain conditions a player casts during some duration, or similar. These effects do not begin immediately. Rather, they begin to apply at the time that player next puts an appropriate spell on the stack, and they apply to that spell. See rule 601.2a.

Some continuous effects affect game rules rather than objects. For example, effects may modify a player’s maximum hand size, or say that a creature must attack this turn if able. These effects are applied after all other continuous effects have been applied. Continuous effects that affect the costs of spells or abilities are applied according to the order specified in rule 601.2f. All other such effects are applied in timestamp order. See also the rules for timestamp order and dependency (rules 613.7 and 613.8).

The controller of a modal spell or activated ability chooses the mode(s) as part of casting that spell or activating that ability. If one of the modes would be illegal (due to an inability to choose legal targets, for example), that mode can’t be chosen. (See rule 601.2b.)

If a spell or ability targets one or more targets only if a particular mode is chosen for it, its controller will need to choose those targets only if they chose that mode. Otherwise, the spell or ability is treated as though it did not have those targets. (See rule 601.2c.)

Some modal spells have one or more modes with a cost listed before the effect of that mode. This indicates that the mode has an additional cost that must be paid as the spell is cast if that mode is chosen. If more than one such mode is chosen, all additional costs must be paid to cast that spell. Paying these costs follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

To cast a spell is to take it from the zone it’s in (usually the hand), put it on the stack, and pay its costs, so that it will eventually resolve and have its effect. A player may cast a spell if they have priority. See rule 601, “Casting Spells.”

Buyback appears on some instants and sorceries. It represents two static abilities that function while the spell is on the stack. “Buyback [cost]” means “You may pay an additional [cost] as you cast this spell” and “If the buyback cost was paid, put this spell into its owner’s hand instead of into that player’s graveyard as it resolves.” Paying a spell’s buyback cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Kicker is a static ability that functions while the spell with kicker is on the stack. “Kicker [cost]” means “You may pay an additional [cost] as you cast this spell.” Paying a spell’s kicker cost(s) follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

If a spell’s controller declares the intention to pay any of that spell’s kicker costs, that spell has been “kicked.” If a spell has two kicker costs or has multikicker, it may be kicked multiple times. See rule 601.2b.

If part of a spell’s ability has its effect only if that spell was kicked, and that part of the ability includes any targets, the spell’s controller chooses those targets only if that spell was kicked. Otherwise, the spell is cast as if it did not have those targets. See rule 601.2c.

Flashback appears on some instants and sorceries. It represents two static abilities: one that functions while the card is in a player’s graveyard and another that functions while the card is on the stack. “Flashback [cost]” means “You may cast this card from your graveyard if the resulting spell is an instant or sorcery spell by paying [cost] rather than paying its mana cost” and “If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack.” Casting a spell using its flashback ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Casting a spell using its madness ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Entwine is a static ability of modal spells (see rule 700.2) that functions while the spell is on the stack. “Entwine [cost]” means “You may choose all modes of this spell instead of just the number specified. If you do, you pay an additional [cost].” Using the entwine ability follows the rules for choosing modes and paying additional costs in rules 601.2b and 601.2f–h.

Splice is a static ability that functions while a card is in your hand. “Splice onto [quality] [cost]” means “You may reveal this card from your hand as you cast a [quality] spell. If you do, that spell gains the text of this card’s rules text and you pay [cost] as an additional cost to cast that spell.” Paying a card’s splice cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Choose targets for the added text normally (see rule 601.2c). Note that a spell with one or more targets won’t resolve if all of its targets are illegal on resolution.

You choose which permanent to sacrifice as you make choices for the spell (see rule 601.2b), and you sacrifice that permanent as you pay the total cost (see rule 601.2h).

Replicate is a keyword that represents two abilities. The first is a static ability that functions while the spell with replicate is on the stack. The second is a triggered ability that functions while the spell with replicate is on the stack. “Replicate [cost]” means “As an additional cost to cast this spell, you may pay [cost] any number of times” and “When you cast this spell, if a replicate cost was paid for it, copy it for each time its replicate cost was paid. If the spell has any targets, you may choose new targets for any of the copies.” Paying a spell’s replicate cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Casting a spell as an effect of its suspend ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Evoke represents two abilities: a static ability that functions in any zone from which the card with evoke can be cast and a triggered ability that functions on the battlefield. “Evoke [cost]” means “You may cast this card by paying [cost] rather than paying its mana cost” and “When this permanent enters, if its evoke cost was paid, its controller sacrifices it.” Casting a spell for its evoke cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Prowl is a static ability that functions on the stack. “Prowl [cost]” means “You may pay [cost] rather than pay this spell’s mana cost if a player was dealt combat damage this turn by a source that, at the time it dealt that damage, was under your control and had any of this spell’s creature types.” Casting a spell for its prowl cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Conspire is a keyword that represents two abilities. The first is a static ability that functions while the spell with conspire is on the stack. The second is a triggered ability that functions while the spell with conspire is on the stack. “Conspire” means “As an additional cost to cast this spell, you may tap two untapped creatures you control that each share a color with it” and “When you cast this spell, if its conspire cost was paid, copy it. If the spell has any targets, you may choose new targets for the copy.” Paying a spell’s conspire cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Retrace is a static ability that functions while the card with retrace is in a player’s graveyard. “Retrace” means “You may cast this card from your graveyard by discarding a land card as an additional cost to cast it.” Casting a spell using its retrace ability follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Casting a spell as an effect of its rebound ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Overload is a keyword that represents two static abilities that function while the spell with overload is on the stack. Overload [cost] means “You may choose to pay [cost] rather than pay this spell’s mana cost” and “If you chose to pay this spell’s overload cost, change its text by replacing all instances of the word ‘target’ with the word ‘each.’” Casting a spell using its overload ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Bestow represents a static ability that functions in any zone from which you could play the card it’s on. “Bestow [cost]” means “As you cast this spell, you may choose to cast it bestowed. If you do, you pay [cost] rather than its mana cost.” Casting a spell using its bestow ability follows the rules for paying alternative costs (see 601.2b and 601.2f–h).

As a spell cast bestowed is put onto the stack, it becomes an Aura enchantment and gains enchant creature. It is a bestowed Aura spell, and the permanent it becomes as it resolves will be a bestowed Aura. These effects last until the spell or the permanent it becomes ceases to be bestowed (see rules 702.103e–g). Because the spell is an Aura spell, its controller must choose a legal target for that spell as defined by its enchant creature ability and rule 601.2c. See also rule 303.4.

Dash represents three abilities: two static abilities that function while the card with dash is on the stack, one of which may create a delayed triggered ability, and a static ability that functions while the object with dash is on the battlefield. “Dash [cost]” means “You may cast this card by paying [cost] rather than its mana cost,” “If this spell’s dash cost was paid, return the permanent this spell becomes to its owner’s hand at the beginning of the next end step,” and “As long as this permanent’s dash cost was paid, it has haste.” Casting a spell for its dash cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Awaken appears on some instants and sorceries. It represents two abilities: a static ability that functions while the spell with awaken is on the stack and a spell ability. “Awaken N—[cost]” means “You may pay [cost] rather than pay this spell’s mana cost as you cast this spell” and “If this spell’s awaken cost was paid, put N +1/+1 counters on target land you control. That land becomes a 0/0 Elemental creature with haste. It’s still a land.” Casting a spell using its awaken ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Surge is a static ability that functions while the spell with surge is on the stack. “Surge [cost]” means “You may pay [cost] rather than pay this spell’s mana cost as you cast this spell if you or one of your teammates has cast another spell this turn.” Casting a spell for its surge cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Emerge represents two static abilities that function while the spell with emerge is on the stack. “Emerge [cost]” means “You may cast this spell by paying [cost] and sacrificing a creature rather than paying its mana cost” and “If you chose to pay this spell’s emerge cost, its total cost is reduced by an amount of generic mana equal to the sacrificed creature’s mana value.” Casting a spell using its emerge ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

You choose which permanent to sacrifice as you choose to pay a spell’s emerge cost (see rule 601.2b), and you sacrifice that permanent as you pay the total cost (see rule 601.2h).

Escalate is a static ability of modal spells (see rule 700.2) that functions while the spell with escalate is on the stack. “Escalate [cost]” means “For each mode you choose beyond the first as you cast this spell, you pay an additional [cost].” Paying a spell’s escalate cost follows the rules for paying additional costs in rules 601.2f–h.

Assist is a static ability that modifies the rules of paying for the spell with assist (see rules 601.2g-h). If the total cost to cast a spell with assist includes a generic mana component, before you activate mana abilities while casting it, you may choose another player. That player has a chance to activate mana abilities. Once that player chooses not to activate any more mana abilities, you have a chance to activate mana abilities. Before you begin to pay the total cost of the spell, the player you chose may pay for any amount of the generic mana in the spell’s total cost.

Jump-start appears on some instants and sorceries. It represents two static abilities: one that functions while the card is in a player’s graveyard and another that functions while the card is on the stack. “Jump-start” means “You may cast this card from your graveyard if the resulting spell is an instant or sorcery spell by discarding a card as an additional cost to cast it” and “If this spell was cast using its jump-start ability, exile this card instead of putting it anywhere else any time it would leave the stack.” Casting a spell using its jump-start ability follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Spectacle is a static ability that functions on the stack. “Spectacle [cost]” means “You may pay [cost] rather than pay this spell’s mana cost if an opponent lost life this turn.” Casting a spell for its spectacle cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Escape represents a static ability that functions while the card with escape is in a player’s graveyard. “Escape [cost]” means “You may cast this card from your graveyard by paying [cost] rather than paying its mana cost.” Casting a spell using its escape ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Mutate appears on some creature cards. It represents a static ability that functions while the spell with mutate is on the stack. “Mutate [cost]” means “You may pay [cost] rather than pay this spell’s mana cost. If you do, it becomes a mutating creature spell and targets a non-Human creature with the same owner as this spell.” Casting a spell using its mutate ability follows the rules for paying alternative costs (see 601.2b and 601.2f–h).

Foretell is a keyword that functions while the card with foretell is in a player’s hand. Any time a player has priority during their turn, that player may pay {2} and exile a card with foretell from their hand face down. That player may look at that card as long as it remains in exile. They may cast that card after the current turn has ended by paying any foretell cost it has rather than paying that spell’s mana cost. Casting a spell this way follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Cleave is a keyword that represents two static abilities that function while a spell with cleave is on the stack. “Cleave [cost]” means “You may cast this spell by paying [cost] rather than paying its mana cost” and “If this spell’s cleave cost was paid, change its text by removing all text found within square brackets in the spell’s rules text.” Casting a spell for its cleave cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Blitz represents three abilities: two static abilities that function while the card with blitz is on the stack, one of which may create a delayed triggered ability, and a static ability that functions while the object with blitz is on the battlefield. “Blitz [cost]” means “You may cast this card by paying [cost] rather than its mana cost,” “If this spell’s blitz cost was paid, sacrifice the permanent this spell becomes at the beginning of the next end step,” and “As long as this permanent’s blitz cost was paid, it has haste and ‘When this permanent is put into a graveyard from the battlefield, draw a card.’” Casting a spell for its blitz cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Casualty is a keyword that represents two abilities. The first is a static ability that functions while the spell with casualty is on the stack. The second is a triggered ability that functions while the spell with casualty is on the stack. Casualty N means “As an additional cost to cast this spell, you may sacrifice a creature with power N or greater,” and “When you cast this spell, if a casualty cost was paid for it, copy it. If the spell has any targets, you may choose new targets for the copy.” Paying a spell’s casualty cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Squad is a keyword that represents two linked abilities. The first is a static ability that functions while the creature spell with squad is on the stack. The second is a triggered ability that functions when the creature with squad enters the battlefield. “Squad [cost]” means “As an additional cost to cast this spell, you may pay [cost] any number of times” and “When this creature enters, if its squad cost was paid, create a token that’s a copy of it for each time its squad cost was paid.” Paying a spell’s squad cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

More Than Meets the Eye represents a static ability that functions in any zone from which the spell may be cast. “More Than Meets the Eye [cost]” means “You may cast this card converted by paying [cost] rather than its mana cost.” Casting a spell using its More Than Meets the Eye ability follows the rules for paying alternative costs (see 601.2b and 601.2f–h). See rule 701.28, “Convert.”

Bargain is a static ability that functions while the spell with bargain is on the stack. “Bargain” means “As an additional cost to cast this spell, you may sacrifice an artifact, enchantment, or token.” Paying a spell’s bargain cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

If a spell’s controller declares the intention to pay that spell’s bargain cost, that spell has been “bargained.” See rule 601.2b.

If part of a spell’s ability has its effect only if that spell was bargained and that part of the ability includes any targets, the spell’s controller chooses those targets only if that spell was bargained. Otherwise, the spell is cast as if it did not have those targets. See rule 601.2c.

A plotted card’s owner may cast it from exile without paying its mana cost during their main phase while the stack is empty during any turn after the turn in which it became plotted. Casting a spell this way follows the rules for paying alternative costs in rules 601.2b and 601.2f–h. A plotted card may be cast this way even if it doesn’t have the plot ability while in exile.

Freerunning is a static ability that functions on the stack. “Freerunning [cost]” means “You may pay [cost] rather than pay this spell’s mana cost if a player was dealt combat damage this turn by a creature that, at the time it dealt that damage, was an Assassin creature or a commander under your control.” Casting a spell for its freerunning cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Gift is a keyword that represents two abilities. It is written “Gift a [something].” The first ability is a static ability that functions while the card with gift is on the stack, and the second is either an ability that functions while the card with gift is on the stack or a triggered ability that functions while the card with gift is on the battlefield. The first ability is always “As an additional cost to cast this spell, you may choose an opponent.” Paying a spell’s gift cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h. The second ability depends on the [something] listed as well as whether the object with the ability is a permanent or an instant or sorcery spell.

Impending is a keyword that represents four abilities. The first is a static ability that functions while the spell with impending is on the stack. The second is static ability that creates a replacement effect that may apply to the permanent with impending as it enters the battlefield from the stack. The third is a static ability that functions on the battlefield. The fourth is a triggered ability that functions on the battlefield. “Impending N—[cost]” means “You may choose to pay [cost] rather than pay this spell’s mana cost,” “If you chose to pay this permanent’s impending cost, it enters with N time counters on it,” “As long as this permanent’s impending cost was paid and it has a time counter on it, it’s not a creature,” and “At the beginning of your end step, if this permanent’s impending cost was paid and it has a time counter on it, remove a time counter from it.” Casting a spell for its impending cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Harmonize represents three static abilities: one that functions while the card is in a player’s graveyard and two that function while the spell with harmonize is on the stack. “Harmonize [cost]” means “You may cast this card from your graveyard by paying [cost] and tapping up to one untapped creature you control rather than paying this spell’s mana cost,” “If you cast this spell using its harmonize ability, its total cost is reduced by an amount of generic mana equal to the tapped creature’s power,” and “If the harmonize cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack.” Casting a spell using its harmonize ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

You choose which creature to tap as you choose to pay a spell’s harmonize cost (see rule 601.2b), and then tap that creature as you pay the total cost.

Warp represents two static abilities that function while the card with warp is on the stack, one of which may create a delayed triggered ability. “Warp [cost]” means “You may cast this card from your hand by paying [cost] rather than its mana cost” and “If this spell’s warp cost was paid, exile the permanent this spell becomes at the beginning of the next end step. Its owner may cast this card after the current turn has ended for as long as it remains exiled.” Casting a spell for its warp cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

“Mayhem [cost]” means “As long as you discarded this card this turn, you may cast it from your graveyard by paying [cost] rather than paying its mana cost.” Casting a spell using its mayhem ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

Web-slinging is a static ability that functions while the spell with web-slinging is on the stack. “Web-slinging [cost]” means “You may cast this spell by paying [cost] and returning a tapped creature you control to its owner’s hand rather than paying its mana cost.” Casting a spell using its web-slinging ability follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

To copy a spell, activated ability, or triggered ability means to put a copy of it onto the stack; a copy of a spell isn’t cast and a copy of an activated ability isn’t activated. A copy of a spell or ability copies both the characteristics of the spell or ability and all decisions made for it, including modes, targets, the value of X, and additional or alternative costs. (See rule 601, “Casting Spells.”) Choices that are normally made on resolution are not copied. If an effect of the copy refers to objects used to pay its costs, it uses the objects used to pay the costs of the original spell or ability. A copy of a spell is owned by the player under whose control it was put on the stack. A copy of a spell or ability is controlled by the player under whose control it was put on the stack. A copy of a spell is itself a spell, even though it has no spell card associated with it. A copy of an ability is itself an ability.

An effect that instructs a player to cast a copy of an object (and not just copy a spell) follows the rules for casting spells, except that the copy is created in the same zone the object is in and then cast while another spell or ability is resolving. Casting a copy of an object follows steps 601.2a–h of rule 601, “Casting Spells,” and then the copy becomes cast. Once cast, the copy is a spell on the stack, and just like any other spell it can resolve or be countered.

A double-faced spell is cast with its front face up by default. See rule 601, “Casting Spells.”
