Feed the Swarm

Destroy target creature or enchantment an opponent controls. You lose life equal to that permanent's mana value.

As an additional cost to cast this spell, sacrifice a creature.
Draw two cards.

Target creature gets -1/-1 until end of turn.
Morbid — That creature gets -13/-13 until end of turn instead if a creature died this turn.

When this creature dies, create a 1/1 white Soldier creature token with lifelink.

When this creature enters, target opponent puts a card from their hand on top of their library.

When this creature dies, create a 1/1 white Spirit creature token with flying.
