Maro's Gone Nuts (CMB2-81) is a green enchantment from the Mystery Booster Playtest Cards 2021 set. Its replacement effect multiplies any effect that would double something, turning a single doubling into quadrupling and stacking multiplicatively with additional copies. The card can serve as a combo amplifier or a powerful rule-modifying piece in decks that care about doubling effects.
