D, Hunter of the Dead

Vigilance
When you cast this spell, exile up to x target creature cards from any graveyard. D enters the battlefield with an additional +1/+1 counter for each card exiled this way.
Whenever another creature enters the battlefield, if it entered from a graveyard or was cast from a graveyard, its controller must pay {3}. If they don't, exile that card and you gain 2 life.
