Dominique Baldwin

Whenever a Creature you control is dealt damage,
you may exile an Instant, Enchantment or
Sorcery card from your graveyard and prevent
that damage being dealt. If you do, put a +1/+1
counter on Dominique Baldwin.
Whenever Dominique Baldwin blocks, put the
top five cards of your library into your graveyard.
As you can see, I know a thing or two about expelling demons.
