Smoky Lounge

2R

Enchantment — Room

At the beginning of your first main phase, add RR. Spend this mana only to cast Room spells and unlock doors. (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.)

Misty Salon

3U

Enchantment — Room

When you unlock this door, create an X/X blue Spirit creature token with flying, where X is the number of unlocked doors among Rooms you control. (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.)
