Sultai Reanimator's plan revolves around graveyard value from Overlord of the Balemurk, Bringer of the Last Gift, and Superior Spider-Man, so Ghost Vacuum is critical to exile key reanimation targets and slow their engine. Duress is weaker here since their key cards are mostly creatures, so it's trimmed for the graveyard hate and for Forsaken Miner, a cheap recurring threat that punishes their slower draws and profitably trades with early blockers. Keep Bitter Triumph and Requiting Hex to answer their big threats before Bringer of the Last Gift's mass-sacrifice reanimation trigger goes off, and hold Deadly Cover-Up as insurance against their graveyard-fueled creature swarm.
