2 rulings from Wizards of the Coast
- 24 November 2014You choose which mode you're using as you put the ability on the stack, after the creature has entered the battlefield. Once you've chosen a mode, you can't change that mode even if the creature leaves the battlefield in response to that ability.
- 24 November 2014If a mode requires a target and there are no legal targets available, that mode can't be chosen. You must choose another mode if able.
