This is a mirror-adjacent blue matchup where Cursed Totem shuts down Psychatog's activated abilities, but otherwise our list is already well-configured to fight a Gush/counterspell deck. Powder Keg comes out since Psychatog's power/toughness scale dynamically with graveyard size, making it awkward to answer with a static mana-value sweeper, and we'd rather hold up interaction. We keep the rest of our core control shell intact since Stasis, Counterspell, and Chain of Vapor are all excellent against their tempo plan.
