Central Elevator // Promising Stairs

The alternate win condition is the tell: assembling eight differently-named unlocked Rooms is a construction project, and this card is both the blueprint and one of the bricks. Central Elevator's front half is a tutor pointed at exactly the resource the back half counts, fetching a Room whose name you don't already control, so it never digs up a duplicate and always advances the tally. The two halves talk to each other in a way most Room cards don't bother with. Promising Stairs sits on the payoff side, buying time with a per-turn surveil while the count climbs and checking the win condition every upkeep once the doors are open. What makes the build genuinely a build rather than a coin flip is the "different names" clause on both sides: the tutor refuses redundancy and the win condition demands variety, so the deck has to run a wide, deliberately unique roster of Rooms rather than four copies of the best one. That mutual constraint is the whole scaffolding of the archetype. Winning through door-count is a slow, telegraphed plan that hands opponents a visible clock, but the elevator's job is to keep that clock ticking without you ever drawing a dead Room, and the stairs' job is to survive long enough to reach the eighth floor.
