A trigger ability (トリガー能力 Torigā nōryoku) is an ability whose effect occurs when a certain event or set of conditions, called a trigger (トリガー Torigā), occurs. A trigger ability is said to activate (発動 hatsudō) when its trigger occurs or is fulfilled. (This is distinct from an ability that is used, as unlike trigger abilities those are invoked manually by the player using them.)
The types of trigger abilities are:
abilities
abilities
Life Burst abilities
Trap abilities- abilities that start with the words "when", "whenever", or "at" (replaced by abilities as of WX-15 Incited Selector; as of the inception of Diva Selection, all such abilities on cards have changed to abilities via errata)
Characteristics of trigger abilities include:
- A trigger ability may be triggered in the middle of an effect. However, it does not activate and resolve until the current effect ends.
- When an effect ends, if there are both trigger abilities and rule-based actions pending, rule-based actions are handled first.
- If multiple trigger abilities from both players were triggered, the turn player's trigger abilities are resolved first. The turn player chooses the order in which their own trigger abilities are resolved until all of the turn player's trigger abilities have been resolved, then the non-turn player chooses the order in which their trigger abilities are resolved. If any abilities trigger after the non-turn player completes the resolution of their abilities, this process repeats.
