Unlicensed Hearse is critical here, exiling Arclight Phoenix from their graveyard so it cannot return to the battlefield via its recursion trigger, while also growing into a real clock. Duress proactively strips a key enabler like Treasure Cruise or a removal spell like Lightning Axe before it threatens your board. Faerie Miscreant and Moon-Circuit Hacker die too easily to their cheap removal suite of Fiery Impulse and Lightning Axe without generating enough value in return. Keep your own removal suite intact to answer Arclight Phoenix on the stack or Picklock Prankster's adventure side, since letting their graveyard plan snowball is the fastest way to lose this race.
