Prismatic Ending is excellent removal for their cheap permanents like Guide of Souls, Ajani, Nacatl Pariah, and Static Prison, exiling anything at or below the number of colors we spend. We keep Swords to Plowshares and Wasteland in to answer their threats and punish their own Wasteland plan, though be mindful that Swords gives their creature's controller life, which can turn on Ocelot Pride's end-step trigger. The slower, clunkier cards come out since this is a grindy board-based matchup where efficient removal matters more.
