If a cost associated with a special action, such as a suspend cost or a morph cost, has an {X} or an X in it, the value of X is chosen by the player taking the special action immediately before they pay that cost.
A spell or ability that creates a token sets both its name and its subtype(s). If the spell or ability doesn’t specify the name of the token, its name is the same as its subtype(s) plus the word “Token.” Once a token is on the battlefield, changing its name doesn’t change its subtype(s), and vice versa.
If an effect instructs a player to create a token that is a copy of a nonexistent object, no token is created (see rule 707, “Copying Objects”). This does not apply to an effect that would use the last known information of an object.
A player who has a card with suspend in their hand may exile that card. This is a special action. A player can take this action any time they have priority, but only if they could begin to cast that card by putting it onto the stack. See rule 702.62, “Suspend.”
Damage dealt to a player by a source without infect causes that player to lose that much life.
Damage dealt to a player by a source with infect causes that source’s controller to give the player that many poison counters.
Damage dealt to a creature by a source with wither and/or infect causes that source’s controller to put that many -1/-1 counters on that creature.
Damage dealt to a creature by a source with neither wither nor infect causes that much damage to be marked on that creature.
Rulings
The declare blockers step is the last chance to cast Devouring Light before creatures deal their combat damage. However, a creature remains an attacking or blocking creature during the combat damage step and end of combat step. Devouring Light may be cast targeting such a creature during those steps, after the creature has dealt combat damage.
When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value.
Tapping a multicolored creature using convoke will pay for {1} or one mana of your choice of any of that creature's colors.
Because convoke isn't an alternative cost, it can be used in conjunction with alternative costs.
If a creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.
You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn.
Tapping an untapped creature that's attacking or blocking to convoke a spell won't cause that creature to stop attacking or blocking.
