Conjuro
Elige uno o ambos: Regresa la carta de criatura objetivo de tu cementerio a tu mano; y/o regresa la carta de encantamiento objetivo de tu cementerio a tu mano.
If you choose both modes, and only one of the cards is still a legal target when Reviving Melody tries to resolve, only that card is returned to your hand.
You choose which mode you're using—or whether to use both modes—as you're casting the spell. Once this choice is made, it can't be changed later while the spell is on the stack.
