Sultai Control leans on discard (Deceit, Rakshasa's Bargain-fueled card advantage), removal (Shoot the Sheriff, Requiting Hex, Deadly Cover-Up), and countermagic (Spell Snare), so Spider-Sense lets us protect our key spells and counter their removal or Deadly Cover-Up at instant speed, while Voice of Victory shuts off their ability to interact on our turn entirely once it resolves. Lost in the Maze is weak here since Sultai doesn't flood the board with creatures, and Prismari Charm's small damage modes rarely matter against this grindy shell, so both are cut along with a copy of Opt to make room. Play patiently, use Spider-Sense to protect our win condition from Deadly Cover-Up, and note Spell Snare only hits mana value 2 spells, so sequence around that when possible.
