Castaway's Despair - Mystery Booster (Common) [MYS-281]

Castaway's Despair is a three-mana Aura from The List that enchants a creature, tapping it upon entry and preventing it from untapping during its controller's untap step. This effectively neutralises a threat for a turn, making it a valuable option in control decks looking to manage the battlefield or in tempo strategies that rely on tempo disruption. However, it does require a creature to target, so it may not always find a suitable target in certain matchups.
