Maro's Gone Nuts (CMB1-81) is a green enchantment from the Mystery Booster Playtest Cards 2019 set. Its replacement effect doubles any effect that already doubles, causing effects that double to quadruple (and more with multiple copies). It functions as a rules-modifying permanent that can dramatically amplify doubling effects in a deck that uses such cards.
