Izzet Sneak and Show vs Sultai Aluren

This is a mirror-adjacent matchup where both decks race to Show and Tell or Aluren into Atraxa; Consign to Memory counters their colorless spells like Lotus Petal activations' triggers are not relevant, but it does stop Acererak's enters/attack triggers and any colorless permanent spell they might slam. Surgical Extraction can remove a copy of Atraxa or Acererak from their deck entirely once one hits a graveyard, denying their most important redundancy. Flusterstorm is less valuable since neither side plays much pure instant/sorcery interaction to counter beyond Force of Will itself, which Flusterstorm can't target. Keep the core combo plan intact and just add resilience.
