5 rulings from Wizards of the Coast
- 24 January 2025If you counter a delayed triggered ability that triggers at the beginning of the “next” occurrence of a specified step or phase, that ability won’t trigger again the following time that phase or step occurs.
- 24 January 2025Abilities that create replacement effects, such as a permanent entering tapped or with counters on it, can’t be targeted. Abilities that apply “as [this creature] enters” are also replacement effects and can’t be targeted.
- 24 January 2025Triggered abilities use the word “when,” “whenever,” or “at.” They’re often written as “[Trigger condition], [effect].” Some keyword abilities, such as prowess and fabricate, are triggered abilities and will have “when,” “whenever,” or “at” in their reminder text.
- 24 January 2025Activated abilities are written in the form “[Cost]: [Effect].” Some keyword abilities, such as equip and crew, are activated abilities and will have colons in their reminder texts.
- 24 January 2025Overcharged Amalgam’s exploit ability can’t target mana abilities. An activated mana ability is one that could add mana as it resolves, doesn’t have a target, and isn’t a loyalty ability. A triggered mana ability is one that could add mana as it resolves and triggers based on an activated mana ability.
