Sultai Aluren is a combo deck relying on Show and Tell, Aluren, and Omniscience to cheat out Atraxa, Grand Unifier or set up Acererak the Archlich loops, so proactive disruption matters more than our usual artifact synergies. Spell Pierce taxes their noncreature enablers like Show and Tell and Aluren while they are tapped low, though it can't touch the creatures themselves. Haywire Mite can be sacrificed to exile a problematic Omniscience or Aluren once it resolves, but its ability costs {G}, which we can only produce with Lotus Petal or Mox Opal, so keep one of those available. We trim slower value artifacts that don't advance a racing or disruptive gameplan against this combo-heavy matchup.
