Moonrise Amalgam

Immolate (Whenever another zombie you control dies, you may exile it instead of putting into your graveyard. If you do, put a +1/+1 counter on this creature.)
Undying (When this creature dies, if it had no +1/+1 counters on it, return it to the battlefield under its owner's control with a +1/+1 counter on it.)
