Jominy

Each creature card in your graveyard has
scavenge. The scavenge cost is equal to its mana
cost. (Exile a creature card from your graveyard
and pay its mana cost: Put a number of +1/+1
counters equal to that card's power on targetcreature.
Scavenge only as a sorcery.)
Sacrifice another creature: Regenerate Jominy
