Melancholy⁣ - Planar Chaos⁣ (Common)⁣ [88]

Melancholy is an Aura that taps the enchanted creature when it enters the battlefield and prevents it from untapping during its controller's untap step. This can effectively neutralise key threats or blockers, forcing your opponent to commit resources to get it back online. However, the need to pay {B} each turn to keep it around may limit its longevity, making it best suited for decks that can consistently generate black mana.
