Duress strips Theorix Charm, Bitter Triumph, or removal before they can disrupt your plan, which matters against a deck full of interactive instants. Torpor Orb shuts off the enters-the-battlefield triggers on Seasoned Cryomancer, Deceit, and Uldaros Theorix, blunting their key value engines. Superior Spider-Man is not stopped by it: it still enters as a copy of a creature card in a graveyard, since that choice is a replacement effect and not a trigger, and its 'When you do, exile that card' reflexive trigger comes from choosing to copy rather than from the creature entering, so Torpor Orb doesn't stop it and the copied card is still exiled. Vren, the Relentless is a strong grindy threat that exiles opposing creatures that would die, leaving Superior Spider-Man and Uldaros Theorix fewer creature cards in their graveyard to copy. Azure Beastbinder is weak since most of their key threats are already powerful 4/4s and 5/5s that shrinking to 2/2 only partially answers, and Shoot the Sheriff and We Say Thee Nay! are too narrow or reactive against their value-creature-heavy plan. Keep Bitter Triumph in since Seasoned Cryomancer and Superior Spider-Man are prime removal targets. Requiting Hex only destroys creatures with mana value 2 or less, so it can't hit either of them and is mostly relevant against an animated Restless Reef.
