Duress strips their Force of Will, Force of Negation, or Swords to Plowshares before we commit threats, which is crucial since they have very little proactive disruption of their own before they stick a Murktide Regent or Tamiyo. Fatal Push kills Tamiyo, Inquisitive Student and Phelia, Exuberant Shepherd cleanly for one mana. Barrowgoyf is a resilient lifelink clock that dodges Swords to Plowshares' upside and grows quickly since both decks fill their graveyards. Malevolent Rumble and Witherbloom Charm are too passive against a controlling deck that wants to grind, and Zuran Orb doesn't affect the board, so all three are cut for more proactive disruption.
