Ornstein and Smough

Undying 4 (When this creature dies, if it had
no +1/+1 counters on it, return it to the battlefield under its owner's control with 4 +1/+1 counters on it.)
When Ornstein and Smough attacks, you
may choose to untap it or give it trample. If
it has a +1/+1 counter on it, choose both.
