Svogthir, the God-Zombie

Eminence — Creature cards in your graveyard
have Dredge X and Scavenge X where X is that
card's mana value.
Svogthir, the God-Zombie's power and toughness
are each equal to the number of creature cards in
your graveyard.
Whenever an ability is used from your graveyard
you may pay {b}{g}, if you do return this card to
the battlefield tapped.
