Adding abilities to objects and removing abilities from objects don’t fall under this rule. (See rule 113.10.)

Mana is produced by the effects of mana abilities (see rule 605). It may also be produced by the effects of spells, as well as by the effects of abilities that aren’t mana abilities. A spell or ability that produces mana instructs a player to add that mana. If mana is produced by a spell, the source of that mana is that spell. If mana is produced by an ability, the source of that mana is the source of that ability (see rule 113.7).

If a spell or ability uses a description of an object that includes the word “source,” it means a source matching that description—a source of an ability, of damage, or of mana—in any zone. See rules 113.7 and 609.7.

An ability can be one of three things:

An ability can be a characteristic an object has that lets it affect the game. An object’s abilities are defined by its rules text or by the effect that created it. Abilities can also be granted to objects by rules or effects. (Effects that grant abilities usually use the words “has,” “have,” “gains,” or “gain.”) Abilities generate effects. (See rule 609, “Effects.”)

An ability can be something that a player has that changes how the game affects the player. A player normally has no abilities unless granted to that player by effects.

An ability can be an activated or triggered ability on the stack. This kind of ability is an object. (See section 6, “Spells, Abilities, and Effects.”)

Abilities can affect the objects they’re on. They can also affect other objects and/or players.

Abilities can be beneficial or detrimental.

An additional cost or alternative cost to cast a card is an ability of the card.

An object may have multiple abilities. If the object is represented by a card, then aside from certain defined abilities that may be strung together on a single line (see rule 702, “Keyword Abilities”), each paragraph break in a card’s text marks a separate ability. If the object is not represented by a card, the effect that created it may have given it multiple abilities. An object may also be granted additional abilities by a spell or ability. If an object has multiple instances of the same ability, each instance functions independently. This may or may not produce more effects than a single instance; refer to the specific ability for more information.

Abilities can generate one-shot effects or continuous effects. Some continuous effects are replacement effects or prevention effects. See rule 609, “Effects.”

There are four general categories of abilities:

Spell abilities are abilities that are followed as instructions while an instant or sorcery spell is resolving. Any text on an instant or sorcery spell is a spell ability unless it’s an activated ability, a triggered ability, or a static ability that fits the criteria described in rule 113.6.

Activated abilities have a cost and an effect. They are written as “[Cost]: [Effect.] [Activation instructions (if any).]” A player may activate such an ability whenever they have priority. Doing so puts it on the stack, where it remains until it’s countered, it resolves, or it otherwise leaves the stack. See rule 602, “Activating Activated Abilities.”

Triggered abilities have a trigger condition and an effect. They are written as “[Trigger condition], [effect],” and include (and usually begin with) the word “when,” “whenever,” or “at.” Whenever the trigger event occurs, the ability is put on the stack the next time a player would receive priority and stays there until it’s countered, it resolves, or it otherwise leaves the stack. See rule 603, “Handling Triggered Abilities.”

Static abilities are written as statements. They’re simply true. Static abilities create continuous effects which are active while the permanent with the ability is on the battlefield and has the ability, or while the object with the ability is in the appropriate zone. See rule 604, “Handling Static Abilities.”

Some activated abilities and some triggered abilities are mana abilities. Mana abilities follow special rules: They don’t use the stack, and, under certain circumstances, a player can activate mana abilities even if they don’t have priority. See rule 605, “Mana Abilities.”

Some activated abilities are loyalty abilities. Loyalty abilities follow special rules: A player may activate a loyalty ability of a permanent they control any time they have priority and the stack is empty during a main phase of their turn, but only if no player has previously activated a loyalty ability of that permanent that turn. See rule 606, “Loyalty Abilities.”

Abilities of an instant or sorcery spell usually function only while that object is on the stack. Abilities of all other objects usually function only while that object is on the battlefield. The exceptions are as follows:

Characteristic-defining abilities function everywhere, even outside the game and before the game begins. (See rule 604.3.)

An ability that states which zones it functions in functions only from those zones.

An ability that states which zones it doesn’t function in functions everywhere except for the specified zones, even outside the game and before the game begins.

An object’s ability that allows a player to pay an alternative cost rather than its mana cost or otherwise modifies what that particular object costs to cast functions on the stack.

An object’s ability that restricts or modifies how that particular object can be played or cast functions in any zone from which it could be played or cast and also on the stack. An object’s ability that grants it another ability that restricts or modifies how that particular object can be played or cast functions only on the stack.

An object’s ability that restricts or modifies what zones that particular object can be played or cast from functions everywhere, even outside the game.

An object’s ability that states it can’t be countered or can’t be copied functions on the stack.

An object’s ability that modifies how that particular object enters the battlefield functions as that object is entering the battlefield. See rule 614.12.

An object’s ability that states counters can’t be put on that object functions as that object is entering the battlefield in addition to functioning while that object is on the battlefield.

An object’s activated ability that has a cost that can’t be paid while the object is on the battlefield functions from any zone in which its cost can be paid.

A trigger condition that can’t trigger from the battlefield functions in all zones it can trigger from. Other trigger conditions of the same triggered ability may function in different zones.

An ability whose cost or effect specifies that it moves the object it’s on out of a particular zone functions only in that zone, unless its trigger condition or a previous part of its cost or effect specifies that the object is put into that zone or, if the object is an Aura, that the object it enchants leaves the battlefield. The same is true if the effect of that ability creates a delayed triggered ability whose effect moves the object out of a particular zone.

An ability that modifies the rules for deck construction functions before the game begins. Such an ability modifies not just the Comprehensive Rules, but also the Magic: The Gathering Tournament Rules and any other documents that set the deck construction rules for a specific format. However, such an ability can’t affect the format legality of a card, including whether it’s banned or restricted. The current Magic: The Gathering Tournament Rules can be found at WPN.Wizards.com/en/rules-documents.

Abilities of emblems, plane cards, vanguard cards, scheme cards, and conspiracy cards function in the command zone. See rule 114, “Emblems”; rule 901, “Planechase”; rule 902, “Vanguard”; rule 904, “Archenemy”; and rule 905, “Conspiracy Draft.”

The source of an ability is the object that generated it. The source of an activated ability on the stack is the object whose ability was activated. The source of a triggered ability (other than a delayed triggered ability) on the stack, or one that has triggered and is waiting to be put on the stack, is the object whose ability triggered. To determine the source of a delayed triggered ability, see rules 603.7d–f.

Once activated or triggered, an ability exists on the stack independently of its source. Destruction or removal of the source after that time won’t affect the ability. Note that some abilities cause a source to do something (for example, “This creature deals 1 damage to any target”) rather than the ability doing anything directly. In these cases, any activated or triggered ability that references information about the source for use while announcing an activated ability or putting a triggered ability on the stack checks that information when the ability is put onto the stack. Otherwise, it will check that information when it resolves. In both instances, if the source is no longer in the zone it’s expected to be in at that time, its last known information is used. The source can still perform the action even though it no longer exists.

The controller of an activated ability on the stack is the player who activated it. The controller of a triggered ability on the stack (other than a delayed triggered ability) is the player who controlled the ability’s source when it triggered, or, if it had no controller, the player who owned the ability’s source when it triggered. To determine the controller of a delayed triggered ability, see rules 603.7d–f.

Activated and triggered abilities on the stack aren’t spells, and therefore can’t be countered by anything that counters only spells. Activated and triggered abilities on the stack can be countered by effects that specifically counter abilities. Static abilities don’t use the stack and thus can’t be countered at all.

Effects can add or remove abilities of objects. An effect that adds an ability will state that the object “gains” or “has” that ability, or similar. An effect that removes an ability will state that the object “loses” that ability.

An effect that adds an activated ability may include activation instructions for that ability. These instructions become part of the ability that’s added to the object.

Effects that remove an ability remove all instances of it.

If two or more effects add and remove the same ability, in general the most recent one prevails. See rule 613 for more information about the interaction of continuous effects.

Effects can stop an object from having a specified ability. These effects say that the object “can’t have” that ability. If the object has that ability, it loses it. It’s also impossible for an effect or keyword counter to add that ability to the object. If a resolving spell or ability creates a continuous effect that would add the specified ability to such an object, that part of that continuous effect does not apply; however, other parts of that continuous effect will still apply, and that resolving spell or ability can still create other continuous effects. Continuous effects created by static abilities that would add the specified ability won’t apply to that object.

An effect that sets an object’s characteristic, or simply states a quality of that object, is different from an ability granted by an effect. When an object “gains” or “has” an ability, that ability can be removed by another effect. If an effect defines a characteristic of the object (“[permanent] is [characteristic value]”), it’s not granting an ability. (See rule 604.3.) Similarly, if an effect states a quality of that object (“[creature] can’t be blocked,” for example), it’s neither granting an ability nor setting a characteristic.

Static abilities create continuous effects, some of which are prevention effects or replacement effects. These effects are active as long as the permanent with the ability remains on the battlefield and has the ability, or as long as the object with the ability remains in the appropriate zone, as described in rule 113.6.

If an effect requires information from the game (such as the number of creatures on the battlefield), the answer is determined only once, when the effect is applied. If the effect requires information from a specific object, including the source of the ability itself, the effect uses the current information of that object if it’s in the public zone it was expected to be in; if it’s no longer in that zone, or if the effect has moved it from a public zone to a hidden zone, the effect uses the object’s last known information. See rule 113.7a. If an ability states that an object does something, it’s the object as it exists—or as it most recently existed—that does it, not the ability.

Awaken

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.

The controller of a spell with awaken chooses the target of the awaken spell ability only if that player chose to pay the spell’s awaken cost. Otherwise the spell is cast as if it didn’t have that target.

If an ability granted by a max speed ability states which zones it functions from, the max speed ability that grants that ability functions from those zones. (See rule 113.6c.)

There are two inherent triggered abilities associated with being the monarch. These triggered abilities have no source and are controlled by the player who was the monarch at the time the abilities triggered. This is an exception to rule 113.8. The full texts of these abilities are “At the beginning of the monarch’s end step, that player draws a card” and “Whenever a creature deals combat damage to the monarch, its controller becomes the monarch.”

There are three inherent triggered abilities associated with having the initiative. These triggered abilities have no source and are controlled by the player who had the initiative at the time the abilities triggered. This is an exception to rule 113.8. The full text of these abilities are “At the beginning of the upkeep of the player who has the initiative, that player ventures into Undercity,” “Whenever one or more creatures a player controls deal combat damage to the player who has the initiative, the controller of those creatures takes the initiative,” and “Whenever a player takes the initiative, that player ventures into Undercity.” See rule 701.49, “Venture into the Dungeon.”

Rad counters are a kind of counter a player can have (see rule 122, “Counters”). There is an inherent triggered ability associated with rad counters. This ability has no source and is controlled by the active player. This is an exception to rule 113.8. The full text of this ability is “At the beginning of each player’s precombat main phase, if that player has one or more rad counters, that player mills a number of cards equal to the number of rad counters they have. For each nonland card milled this way, that player loses 1 life and removes one rad counter from themselves.”

Planechase games have an inherent triggered ability known as the “planeswalking ability.” The full text of this ability is “Whenever you roll the Planeswalker symbol on the planar die, planeswalk.” (See rule 701.31, “Planeswalk.”) This ability has no source and is controlled by the player whose planar die roll caused it to trigger. This is an exception to rule 113.8.

Some cards have an ability that states the card can be your commander. This ability modifies the rules for deck construction, and it functions before the game begins. See also rule 113.6n.
