This is a mirror-ish blue-based tempo matchup where Force of Negation gives you a second axis of free interaction on their turn to protect your own threats or stop their noncreature spells like Thoughtseize and Flow State. Stifle is much weaker here since they don't rely heavily on activated/triggered abilities worth countering. Surgical Extraction is strong after answering a key card like Bilbo, Thief in the Night, stripping followups and graveyard fuel. We're trimming one Karakas since their legendary creature count (Bilbo, Thief in the Night) is lower value to bounce compared to the free interaction Force of Negation provides.

Eldrazi is a colorless creature-based ramp deck full of big threats like Reality Smasher and Thought-Knot Seer, so Force of Negation is excellent as a free counter for their Kozilek's Command or Chalice of the Void on the draw. Consign to Memory does hit their colorless spells since Eldrazi is largely colorless, but Force of Negation is more proactive and can stop a game-ending Kozilek's Command. Keep the rest of the countermagic suite intact since Force of Will and Daze remain crucial against their fast, colorless clock.

Ocelot Pride wants to flood the board with token cats and pump Ajani, so sweepers and unconditional exile are far better than tempo counterspells here. Wrath of the Skies can be scaled to blow up their whole board of small tokens and Guide of Souls, while Prismatic Ending picks off Ajani, Nacatl Pariah or Thalia, Guardian of Thraben for cheap. Celestial Purge exiles any red permanent they bring in (Amped Raptor). Daze is weak since they aren't relying on a single fragile threat, and Consign to Memory only hits colorless spells or triggered abilities, which is narrow against their mostly white/colored permanents.
