Spontaneous Mutation (EMN 74, foil) is a blue Enchantment — Aura from the Eldritch Moon set. It has Flash, enchants a creature, and gives the enchanted creature -X/-0 where X equals the number of cards in your graveyard, with X updating as the graveyard changes. As a cheap, instant-speed debuff it can disrupt large attackers or combine with graveyard manipulation to scale its effect.
