Nefti, Patron Seeker

Whenever a demon, god or planeswalker card
enters the battlefield under your control,
you may put a +1/+1 counter on Nefti, lose 1
life, and draw 2 cards.
{t}: Exile target creature from your graveyard.
Search your library for a demon with a
converted mana cost equal to or less than the
exiled creature's converted mana cost plus {2} and put it into the battlefield tapped.
