Master Monstrosity

Lifelink
Whenever you cast a spooky spell, you may
remove a counter from Master Monstrosity. If
you do, it 2 damage to target creature. (Spirits,
Zombies, Skeletons and Horrors are spooky.)
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.)
