Mark, The Undertaker
Whenever a creature dies, target player puts the top 4 cards of his
or her library into his or her graveyard.
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 can not kill that which is already dead."
