MTG Salvation

9/29/2017 You must choose another target creature (if able) as Atzocan Archer’s triggered ability is put on the stack. You choose as that ability resolves whether those creatures fight.

9/29/2017 If Atzocan Archer isn’t on the battlefield as its triggered ability resolves, or if the target of that ability is illegal, no creature will deal or be dealt damage.

9/29/2017 Atzocan Archer’s ability can target another creature you control (such as a Dinosaur with an enrage ability).
