Damien of the Crows of Murder

Damien has power equal to the number of cards
in your graveyard and toughness equal to the
number of cards in your hand.
Whenever another creature dies, you may draw a
card. If you do, discard a card. That card can be
cast from your graveyard for its mana cost until
the end of your next turn.
"The sound of my murder is a call to action for the
dead and a dire warning for those in my path. Tread lightly or you will join them"
