Sultai Aluren is a glass-cannon combo deck that doesn't interact with your graveyard, so this matchup is about who assembles their engine first rather than grinding; Poxwalkers and extra discard-fodder matter less than speeding up your own kill. Silent Gravestone can come in as a cheap artifact that doesn't slow your plan much while protecting your Bridge from Below and Narcomoeba triggers from any incidental graveyard hate they bring in (Faerie Macabre). Kiora's Dismissal can bounce their Aluren or Omniscience back to hand on your turn if you're ever racing and need to buy a turn, since both are enchantments. Prioritize goldfishing your Cabal Therapy/Dread Return kill as fast as possible rather than boarding for interaction.
