Remnant

Trample
Persist(When this creature is put into a graveyard from the battlefield, 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.)
When Remnant enters the battlefield, remove a -1/-1 counter from it and put 3 eliminate counters on it. At the beginning of your upkeep, remove an eliminate counter from Remnant. If at any time Remnant has no eliminate counters on it, exile it.
