- 5 October 2018You choose the target of the triggered ability as it goes on the stack, but you choose whether the creatures fight as that ability resolves.
- 5 October 2018If the target creature is an illegal target when Affectionate Indrik's ability tries to resolve, the ability doesn't resolve. If Affectionate Indrik is no longer on the battlefield, the target creature won't deal or be dealt damage.
