Central Elevator // Promising Stairs - Duskmourn: House of Horror - 44

Enchantment — Room

Mana Cost: {3}{U}

When you unlock this door, search your library for a Room card that doesn't have the same name as a Room you control, reveal it, put it into your hand, then shuffle.
(You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.)
