Dimir Tempo leans on Daze and Force of Will to protect a single resilient threat, so Surgical Extraction lets us proactively strip their Murktide Regent or Nethergoyf out of hand/library after seeing it once, and it also answers their own graveyard plan. Cutting Shallow Grave and some Collective Brutality reduces our reliance on fragile, easily-Daze'd reanimation spells that die to their efficient interaction; keep Unmask and Thoughtseize maxed since discard is at a premium against their countermagic. Witherbloom Apprentice adds incidental life-drain pressure that helps race their clock once our reanimation targets get through.

Ocelot Pride Midrange grinds with token generation and Wasteland/Karakas disruption, so Chain of Smog's double discard helps strip their hand of key pieces like Ajani, Nacatl Pariah or Swords to Plowshares answers for our reanimated threats, and it can escalate into a two-for-one if they have no hand left. Surgical Extraction can proactively remove a problematic Orcish Bowmasters or disrupt their own graveyard-adjacent cards. Cabal Therapy is weaker here since it is a one-shot effect against a deck that rebuilds hand advantage quickly, and some Lotus Petals come out since we are less reliant on turn-one explosiveness in a grindier matchup; keep the full Thoughtseize/Unmask suite to protect our reanimation targets from Swords to Plowshares.

Izzet Delver races with Dragon's Rage Channeler and Murktide Regent backed by Force of Will, Daze, and Lightning Bolt, so trimming fragile, easily-interacted-with cards like Shallow Grave and some Collective Brutality tightens our plan around resilient reanimation (Animate Dead, Reanimate) and discard. Surgical Extraction can exile the instants and sorceries in their graveyard that fuel Murktide Regent's delve and Dragon's Rage Channeler's delirium, hitting any copies in their hand and library too, which slows their best threats significantly. Witherbloom Apprentice is a cheap body providing incidental life drain to offset their burn-based damage race; keep Thoughtseize and Unmask at full count since proactive discard is crucial against their countermagic suite.
