5 rulings from Wizards of the Coast
- 4 October 2019If an effect copies an Adventure spell, that copy is exiled as it resolves. It ceases to exist as a state-based action; it's not possible to cast the copy as a creature.
- 4 October 2019Lucky Clover's ability and the copy it creates both resolve before the Adventure spell. They resolve even if the Adventure spell is countered before the copy is created.
- 4 October 2019The copy will have the same targets as the spell 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).
- 4 October 2019Lucky Clover can copy any Adventure spell, not just one with targets.
- 4 October 2019The copy is created on the stack, so it's not “cast.” Abilities that trigger when a player casts a spell won't trigger.
