A Room card enters with only one door available, and unlocking the other half means paying its cost, on your terms, later or never. This five-color Warlock rewrites that arithmetic. The tap ability lets you lock or unlock any door of a Room you control for free, resetting a locked half so an unlock-on-enter effect can fire again or swinging open the expensive side you had shelved. That is the subtler of its two design ideas. The enters-the-battlefield dig is the loud one: reveal seven, keep every enchantment among them, and refill your hand around the exact permanent type the deck is built on. Because Rooms are enchantments, that trigger feeds the very engine the tap ability manipulates. The sorcery-speed clamp holds it to one manipulation per turn, a deliberate main-phase choice rather than an instant-speed loop that would break the door economy open. Five colors is a steep price for a 3/5 body, but the stats were never the point. This is a design that treats Rooms as a resource to be cycled and re-triggered rather than a mana sink you pay off once and forget, and that reframing pays back the WUBRG manabase it demands.
