Dimir Tempo leans on Daze and Force of Will to tax or outright counter our combo pieces, so redundant tutor chains that use up multiple cards per activation (Transmute Artifact) get trimmed for a second Mystic Forge, since drawing into free casting from the top of the library is harder for them to interact with piece by piece. Archive Arbiter comes in to destroy problematic noncreature permanents like a resolved Kaito or gain 4 life to blunt their clock while providing a 4/4 flying body that dodges their small creatures. Paradox Engine gives us a second copy to find, letting a single resolved artifact chain into an immediate untap-everything turn before they can Wasteland us off mana. Keep the full Ancient Tomb/Urza's land package intact since Wasteland pressure makes mana resilience critical.

Ocelot Pride Midrange's engine hinges on cheap recurring value from Ocelot Pride and Guide of Souls, plus Wasteland denying our nonbasic-heavy manabase, so Disruptor Flute naming Wasteland or Ocelot Pride taxes their most important repeatable effects by {3} without needing to interact on the stack. We trim one copy each of Transmute Artifact, Tezzeret, Cruel Captain, and Mishra's Research Desk since this is a grindy matchup where slowing their engine matters more than maximizing combo speed. Keep Kozilek's Command in since exiling a creature for X still answers an early Ocelot Pride or Ajani before it snowballs. The full mana base stays untouched given their Wasteland count.

Sultai Aluren wants to flood the board with free creatures off Aluren or cheat in Atraxa, Grand Unifier via Show and Tell, so Ensnaring Bridge is excellent insurance since our hand will often be low after deploying artifacts, shutting down their wide boards of small Aluren creatures. Mycosynth Lattice turns all their lands into artifacts, letting Karn, the Great Creator's static ability shut off problematic activated abilities on their side while still letting our own mana engine function. We trim a Transmute Artifact and Tezzeret, Cruel Captain since this matchup is more about surviving their critical mass of threats than chaining tutors efficiently. Force of Will is still a real concern, so keep redundant cheap artifacts (Lotus Petal, Grim Monolith) in to play around countermagic.
