Vengeance

Flying, deathtouch
Vengeance enters the battlefield with three
+1/+1 counters. If damage would be dealt to
Vengeance, prevent that damage, remove a
+1/+1 counter from it and Vengeance deals
1 damage to each creature the source of that
damage controls.
When Vengeance has no counters on it, exile
it and return it to the battlefield flipped.
