Chalice of the Void is awkward here since it hits our own Ancient Tomb-fueled artifacts as much as theirs, and their curve of Thoughtseize/Brainstorm/Ponder at one mana means a Chalice for zero is symmetric at best. Consign to Memory counters their free spells (Force of Will, Daze) for one mana and stops flipped Tamiyo's abilities and Murktide Regent's delve-fueled casting cost issues indirectly by tempo, while extra Force of Negation protects our own threats and answers their Murktide or Kaito. Tormod's Crypt strips Murktide Regent's delve fuel and Nethergoyf/Barrowgoyf-style graveyard value, crippling their best late-game threat. Sink into Stupor comes out since bouncing their cheap Tamiyo or Kaito is low-impact against a deck that can just replay it, and Chalice trims because our own affinity shell is faster and more mana-hungry than the effect is worth against their low curve.

Ocelot Pride Midrange goes wide with cheap creatures (Ocelot Pride, Guide of Souls, Amped Raptor tokens) that Dismember cleanly answers at -5/-5, killing anything they're likely to play outside Voice of Victory's token shell. Pithing Needle can shut down Ocelot Pride's end-step token trigger is actually a triggered ability not activated, so Needle won't stop it directly, but it is excellent against Wasteland, Karakas returning legendary creatures, or a resolved Ajani, Nacatl Pariah's activated loyalty abilities; bring it in mainly for Wasteland/Karakas disruption. Haywire Mite answers their Static Prison or Goblin Bombardment (noncreature artifacts/enchantments) if needed, though it requires green mana we don't have, so treat it as a marginal add only if testing shows a specific need — otherwise favor Dismember count. Chalice of the Void is weak since their curve is spread from one to four mana with key one-drops like Guide of Souls and Ocelot Pride, making a low Chalice symmetric against our own Ancient Tomb-fueled artifacts, so it comes out; Krang trims slightly since it's clunky against Swords to Plowshares and Wasteland-heavy disruption.

Consign to Memory gives us crucial interaction against their win condition by targeting Thassa's Oracle's triggered ability or countering colorless spells like Lion's Eye Diamond and Lotus Petal. Chalice of the Void set at one is tempting, but while Dark Ritual is one mana value and Lion's Eye Diamond is zero, Doomsday itself has a mana value of three, and Chalice is symmetric and risky against our own Lotus Petal/Mox Opal engine, so it comes out. Extra Force of Negation lets us pitch a blue card to counter their Doomsday itself for free, which is our single best interaction point. Hydroblast has no legal targets in this matchup since the opponent has no red cards, so it stays out of the plan; Kappa Cannoneer is one of our slowest, most tap-out threats and is cut since we want to hold up interaction rather than overextend into Daze/Force of Will.
