Flesh, Blood and Bone

Cast this spell only if a opponent lost life this turn. As a additional cost, sacrifice a creature you control, and exile a creature form your graveyard.
Put the dark permanent from your graveyard in play under your control.
"Bone of the father, unknowingly given, you will renew your son! Flesh of the servant, willingly sacrificed, you will revive your master. Blood of the enemy, forcibly taken, you will resurrect your foe."
