When Michelangelo enters, create a Mutagen token. (It's an artifact with "{1}, {T}, Sacrifice this token: Put a +1/+1 counter on target creature. Activate only as a sorcery.") If one or more +1/+1 counters would be put on a creature you control, that many plus one +1/+1 counters are put on it instead.
