There are 16 rooms cards in the set so far. If you get Central Elevator you can tutor room cards, and you can use her to reset that room for repeat searches. Promising Staircase is also an alt win con for her that comes attached to your tutor engine and lets you better set her up for an ETB trigger through surveil 1 on upkeeps.

First tutor would likely be Bottomless Pool so you could pay {U} to bounce her to hand, recast her to refill your hand, and then following turns to reset a bounce engine.
