One ruling from Wizards of the Coast
- 14 April 2023You don't have to choose a target to activate the last ability. However, if you do, and that target is illegal at the time the ability tries to resolve, it won't resolve and none of its effects will happen. Slimefoot and Squee won't be returned to the battlefield.
