Magnetic Mountain (SUM-163) is a red enchantment from the Summer Magic / Edgar set. It prevents blue creatures from untapping during their controllers' untap steps and offers a paid upkeep option allowing each player to pay {4} per tapped blue creature they choose to untap during their own upkeep. As a global effect that targets a color, it can be used to disrupt blue-heavy strategies or to create interactive timing choices around untapping for both players.
