↑ Section 603. Handling Triggered Abilities
603.7 An effect may create a delayed triggered ability that can do something at a later time. A delayed triggered ability will contain “when,” “whenever,” or “at,” although that word won’t usually begin the ability.
- 603.7a Delayed triggered abilities are created during the resolution of spells or abilities, as the result of a replacement effect being applied, or as a result of a static ability that allows a player to take an action. A delayed triggered ability won’t trigger until it has actually been created, even if its trigger event occurred just beforehand. Other events that happen earlier may make the trigger event impossible. Example: Part of an effect reads “When this creature leaves the battlefield,” but the creature in question leaves the battlefield before the spell or ability creating the effect resolves. In this case, the delayed ability never triggers. Example: If an effect reads “When this creature becomes untapped” and the named creature becomes untapped before the effect resolves, the ability waits for the next time that creature untaps.
- 603.7b A delayed triggered ability will trigger only once—the next time its trigger event occurs—unless it has a stated duration, such as “this turn.” If its trigger event occurs more than once simultaneously and the ability doesn’t have a stated duration, the controller of the delayed triggered ability chooses which event causes the ability to trigger.
- 603.7c A delayed triggered ability that refers to a particular object still affects it even if the object changes characteristics. However, if that object is no longer in the zone it’s expected to be in at the time the delayed triggered ability resolves, the ability won’t affect it. (Note that if that object left that zone and then returned, it’s a new object and thus won’t be affected. See rule 400.7.) Example: An ability that reads “Exile this creature at the beginning of the next end step” will exile the permanent even if it’s no longer a creature during the next end step. However, it won’t do anything if the permanent left the battlefield before then. (refs: 400.7)
- 603.7d If a spell creates a delayed triggered ability, the source of that delayed triggered ability is that spell. The controller of that delayed triggered ability is the player who controlled that spell as it resolved.
- 603.7e If an activated or triggered ability creates a delayed triggered ability, the source of that delayed triggered ability is the same as the source of that other ability. The controller of that delayed triggered ability is the player who controlled that other ability as it resolved.
- 603.7f If a static ability generates a replacement effect which causes a delayed triggered ability to be created, the source of that delayed triggered ability is the object with that static ability. The controller of that delayed triggered ability is the same as the controller of that object at the time the replacement effect was applied.
- 603.7g If a static ability allows a player to take an action and creates a delayed triggered ability if that player does so, the source of that delayed triggered ability is the object with that static ability. The controller of that delayed triggered ability is the same as the controller of that object at the time the action was taken.
- 603.7h An activated or triggered ability may create a delayed triggered ability that triggers when the ability that created it has resolved a certain number of times in a turn. In that case, that delayed triggered ability is created only once, during the appropriate resolution of that ability.
