Legendary Creature — Hydra Horror

Oracle Text

Grakmaw enters with three +1/+1 counters on it.\nWhenever another creature you control dies, if it had a +1/+1 counter on it, put a +1/+1 counter on Grakmaw.\nWhen Grakmaw dies, create an X/X black and green Hydra creature token, where X is the number of +1/+1 counters on Grakmaw.
