Wolf of the Waxing Moon

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.)
Whenever a permanent you control transforms into a non-Human creature, you may remove a +1/+1 counter or -1/-1 counter from target creature.
