Glimmerdust Nap⁣ - Lorwyn⁣ (Common)⁣ [68]

Glimmerdust Nap enchants a tapped creature, preventing it from untapping during its controller's next untap step. This can effectively neutralise key threats or blockers for a turn, providing tempo advantage in blue-based control or tempo decks. However, it only affects creatures that are already tapped, limiting its use against active threats.
