Each Room card has two halves called "doors." When casting: - Choose one door to unlock - Pay the mana cost of the chosen half - Only the unlocked half's abilities apply After a Room is on the battlefield: - Unlock the other door by paying its mana cost as a sorcery - Unlocking is a special action that doesn't use the stack - Both halves' abilities become active after unlocking If a Room enters without being cast: - Both doors start locked - Unlock either door by paying its mana cost as a sorcery Characteristics of a Room card: - On battlefield: Based on unlocked door(s) - In other zones: Combined characteristics of both halves Copying a Room: - Copy has the same doors unlocked as the original - Locked doors of the copy can be unlocked later Dollmaker's Shop // Porcelain Gallery As a two-drop, Dollmaker's Shop is an efficient token generator that's already quite exciting in Commander
The core pieces beyond the three-cost characters center on Merlin Rabbit and Goat
Delirium was also a core mechanic of the next set in this block, Eldritch Moon , which featured Emrakul's emergence into the plane and subsequent warping of the plane into a Lovecraftian horror: Since its original printing, Delirium has shown up as a mechanic in only a few other Magic sets, Modern Horizons 2 and 3 , and Duskmourn: House of Horror

Interestingly, this is a functional reprint of a card in green that does the exact same thing, Parallel Lives (mentioned below)
