Hi, if I am casting necropanther for it's mutate cost. Trying to mutate a 1/1 cat token. Can the opponent kill the token in response with a fatal push, so I cannot mutate it?
If the Mutate target is removed, the Necropanther enters the battlefield as a regular creature. Its "whenever this creature mutates" ability doesn't trigger (but you can later use another creature's Mutate on Necropanther to trigger it).
if a mutating creature spell tries to resolve but can't because its target is illegal or has gone missing, the mutating creature spell will simply resolve and enter the battlefield. So, it's not quite an "all Dinosaur eggs in one basket" kind of risk. One note though: although the spell resolves and the creature enters the battlefield, any "Whenever this creature mutates" abilities it has won't trigger.
thanks. If I mutate a necropanther with another necropanther. Do I put two creatures from the graveyard back to play?
Yes.
The resulting creature will have two separated abilities, both with the same text, "Whenever this creature mutates, return target creature card with converted mana cost 3 or less from your graveyard to the battlefield". Both abilities trigger and resolve separately, as the creature did mutate.
