Black Hand, the Corpse Caller

Spells you cast from your graveyard have cascade.
(When you cast the spell, exile cards from the top of
your library until you exile a nonland card that costs
less. You may cast it without paying its mana cost.
Put the exiled cards on the bottom of your library in a random order.)
Whenever Black Hand, the Corpse Caller deals
combat damage to a player you may mill that
many cards.
