Dimir Tempo is a cantrip-and-free-counterspell mirror where protecting our threats and disrupting theirs matters more than symmetrical value engines. Force of Negation lets us fight through their Force of Will/Daze protection on key turns for free, while Spell Snare picks off their two-mana cards like Orcish Bowmasters and Ponder-adjacent plays. Teferi comes out because his static ability does little against a deck full of instants and free spells, and Consign to Memory is weaker here since they run few colorless spells or relevant triggered abilities worth countering. Keep Stifle in to blunt Tamiyo flips and fetchland value.

Ocelot Pride Midrange goes wide fast with token generators like Ocelot Pride, Guide of Souls, and Ajani, so we need sweepers and flexible exile effects rather than tempo plays. Wrath of the Skies can scale with energy to wipe their board of small Cats and other low-cost permanents, while Prismatic Ending with two colors of mana can exile key noncreature permanents like Static Prison or a planeswalker. Daze is weak here since we don't want to bounce our own lands against an aggressive, disruption-heavy deck, and one Stifle comes out since their relevant triggers (Ocelot Pride's token creation, Ajani's transform) aren't the best Stifle targets. Keep Swords to Plowshares and Teferi, Time Raveler in to handle individual threats and shut off their instant-speed disruption.

Sultai Aluren is a combo-control deck that wins via Show and Tell into Omniscience/Atraxa or by assembling Aluren, so proactive free interaction that fights through Force of Will is critical. Force of Negation lets us counter their Show and Tell or combo pieces even on their turn for free. Containment Priest is excellent since it shuts off Aluren's free-casting loophole (creatures must be cast, and Priest exiles any nontoken creature that enters without being cast) and also stops Show and Tell shenanigans involving creatures. Snapcaster Mage is a lower-impact body against a deck not fighting on the stack with small interaction, so it comes out alongside some Consign to Memory, which has fewer colorless targets here.
