Jeskai Control wants to resolve Jeskai Revelation and grind with Stock Up and Great Hall of the Biblioplex, so Duress proactively strips removal like Fire Magic or countermagic like Negate before they can use it. Gideon the Oathless is a resilient threat that punishes them every time they deploy a blocker and survives their single-target removal suite better than fragile creatures. Samut's haste is less valuable against a deck full of sweepers like Day of Judgment and Deadly Cover-Up, and Stinging Vitriol's small damage and discard are outclassed by Duress's proactive disruption. Play around their sweepers by not overextending into Pyroclasm or Deadly Cover-Up range.
