Eldrazi's gameplan is grindy ramp into Emrakul, the Promised End and Devourer of Destiny, so Wrath of the Skies gives you a scalable answer to their board while Teferi, Time Raveler stops them from casting instants like Dismember and Kozilek's Command at instant speed, including in response to your graveyard plan. Thoughtseize is weak since they're a creature/land deck with few proactive spells to strip, and Force of Negation is clunky against a deck that isn't casting many relevant noncreature spells on your turn. Pest Control is mostly dead since it only hits their mana value 1 or less permanents (Eldrazi Spawn tokens and a handful of cheap artifacts) and misses the creatures that actually matter. Damping Sphere slows down Eldrazi Temple and Ugin's Labyrinth mana acceleration, since lands tapped for two mana only produce a single {C}, buying time for your Atraxa, Grand Unifier and Goryo's Vengeance plan to take over.

Rakdos Delirium relies heavily on its graveyard for Nethergoyf sizing, Street Wraith cycling, and escape/delirium payoffs, so Nihil Spellbomb both disrupts their graveyard plan and cantrips later; just sequence carefully since you still need your own graveyard for Goryo's Vengeance targets. Pest Control answers their cheap permanents like Stitcher's Supplier and Mishra's Bauble for extra value. Faithful Mending comes out since you want to leave up interaction and graveyard disruption rather than dig for more cards against such an aggressive, disruptive clock, and one Thoughtseize is cut since they're often tapped out casting their own proactive spells by the time you'd want it. Keep Solitude and Psychic Frog as your main stabilizers against their aggressive curve.

Consign to Memory is narrower than it first looks: it only counters a triggered ability or a colorless spell. Day's Undoing, Jace, the Mind Sculptor, Teferi, Time Raveler and Narset are blue or multicolored, and Solitude, the Wraths and Supreme Verdict are white, so none of those spells can be hit. It does have real targets, though. The enter trigger of their Solitude (hard-cast or evoked) is a triggered ability, so Consign can stop it from exiling your Atraxa, Grand Unifier or Griselbrand. The only colorless spell it can counter is Isochron Scepter, and it can also answer Scepter's imprint trigger. Mystical Dispute is live against their Teferi, Time Raveler, Narset, Parter of Veils, Day's Undoing, counterspells, and Jace, the Mind Sculptor, and it costs only {1} against any of those blue spells. It cannot counter Supreme Verdict. Thoughtseize loses value once they're tapped out for their own disruption-heavy turns and they have so many answers already in hand from Orim's Chant/Silence lines. Prismatic Ending is also weaker here: their important permanents are Teferi and Narset at mana value 3 and Jace at 4, which are harder to Converge away cheaply, and it can't touch sorceries like Supreme Verdict, Wrath of the Skies or Day's Undoing at all. Keep Force of Negation and the Goryo's Vengeance package intact since resolving Atraxa, Grand Unifier or Griselbrand still wins the attrition war.
