Returned Warrior

When Returned Warrior enters the battlefield,
you may sacrifice another creature. If you do,
choose an opponent. You and that player each
draw two cards and lose two life.
Remove a -1/-1 counter from Returned Warrior:
Create a 2/2 black zombie creature.
Persist (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.)
