6 rulings from Wizards of the Coast
- 18 July 2014A mana ability is an ability that (1) could add mana when it resolves, (2) isn't a loyalty ability, and (3) doesn't require a target.
- 18 July 2014The copy will have the same targets as the ability it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).
- 18 July 2014Activated abilities are written in the form "Cost: Effect." Some keywords are activated abilities and will have colons in their reminder texts.
- 18 July 2014If the ability is modal (that is, it says "Choose one —" or the like), the copy will have the same mode. You can't choose a different one.
- 18 July 2014If the ability has {X} in its cost, the value of X is copied.
- 18 July 2014If paying the activation cost of the ability includes sacrificing Kurkesh, the ability won't be copied. At the time the ability is considered activated (after all costs are paid), Kurkesh is no longer on the battlefield.
