Permeating Mass (EMN 165, foil) is a one-mana green Creature — Spirit from the Eldritch Moon set. Whenever it deals combat damage to a creature, that damaged creature becomes a copy of Permeating Mass. This creates a propagating effect where newly copied creatures also gain the same ability, potentially spreading the effect across the battlefield.
