Gual, Bringer of the Dead

Zombies you control have, 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.)
You may put a zombie card from your graveyard
onto the battlefield by paying 2 life.
If a creature you control were to die, you may
pay {c}{b}, if you don't, exile that creature.
