Ertha Jo, Frontier Mentor Rulings
5 most recent
- Apr 12, 2024 Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keyword abilities (such as equip) are activated abilities and will have colons in their reminder text.
- Apr 12, 2024 Any choices made when the ability resolves won't have been made yet when it's copied. Any such choices will be made separately when the copy resolves.
- Apr 12, 2024 If an ability is linked to a second ability, copies of that ability are also linked to that second ability. If the second ability refers to "the exiled card," it refers to all cards exiled by the ability and the copy. For example, if one of Helvault's activated abilities is copied and two cards are exiled, they both return when Helvault is put into a graveyard from the battlefield.
- Apr 12, 2024 If the ability divides damage or distributes counters among a number of targets, the division and number of targets can't be changed. If you choose new targets, you must choose the same number of targets.
- Apr 12, 2024 If the ability is modal (that is, if it says, "Choose one —" or similar), the mode is copied and can't be changed.
