Reina Roja economy denial deck, with Caïssa to taste. Reina, Rook, and Xanadu are for preventing ice from being rezzed; Knight and the other breakers are for when plan A fails. Shutdowns to induce hear-tearing, Pawn and Deja Vu for program recovery.
I considered the strength-reduction suite with Bishop. Datasucker, Ice Carver, and some combination of Yog.0, Darwin, and Mimic, but it was frankly a lot of cards that don't necessarily play well with Knight.
