Fatal Push is weak since Esper Control runs few cheap creatures, so trim a couple copies. Consign to Memory counters a triggered ability or a colorless spell, which gives it narrow but real targets here, like the enters trigger on Solitude or their colorless Isochron Scepter. Planeswalker loyalty abilities are activated abilities, so it cannot stop those. It is mainly there as flexible countermagic they can't easily play around. Mystical Dispute is excellent here, taxing their blue spells like Teferi, Narset, Jace, or Day's Undoing for just one mana, since it costs {2} less when it targets a blue spell. It counters the spell unless they pay {3}. Prismatic Ending is the most marginal of these cards: it can only exile their planeswalkers like Narset and Teferi if you spend three colors of mana, so it comes out for more impactful interaction. Keep Thoughtseize and Orcish Bowmasters, which are strong against their hand-dependent plan, with Bowmasters also punishing extra draws from cards like Day's Undoing or Jace.
