Sultai Aluren aims to cheat in Atraxa, Grand Unifier via Show and Tell or chain into Acererak the Archlich and Aluren loops, protected by Force of Will, so Disruptor Flute naming Show and Tell or Aluren directly taxes their key enablers. Tormod's Crypt offers only minor disruption, since their primary plan is cheating creatures into play rather than reanimating them. Defense Grid is weak since Show and Tell is frequently cast on their own turn, and Pithing Needle has few relevant targets beyond their fetchlands, since their engine runs on spells rather than activated abilities. Karakas stays in, because Atraxa and Acererak are both legendary creatures and Karakas can return either one to its owner's hand. To keep the swap even, shave a Manifold Key instead. Focus on resolving The One Ring and Karn, the Great Creator quickly, since outracing their Atraxa-fueled card advantage is often more reliable than trying to answer it piece by piece.
