Carlisle Cullen

Carlisle Cullen cannot deal damage to Humans.
If a Human you control would die, exile it with
three Venom Counters. At the start of each
upkeep, remove a Venom Counter. When
there are no Venom counters, return it to the battlefield
under its owner's control with Haste and three
+1/+1 counters. It is now a Newborn Vampire
instead of its other types.
