Plotting Henchman

At the beginning of your end step, you may remove a -1/-1 counter from Plotting Henchman. If you do, put a -1/-1 counter on target creature.
Persist (When this creature is put into a graveyard from play, if it had no -1/-1 counters on it, return it to play under its owner's control with a -1/-1 counter on it.)
