This opponent's game plan revolves around Stasis locking the board while Forsaken City and their Islands generate mana advantage, so Aura of Silence is excellent both as a tax on Stasis and Powder Keg and as a way to blow up Stasis outright once it resolves. Enlightened Tutor finds whichever artifact or enchantment answer you need most, typically Aura of Silence against Stasis or Cursed Totem to strand their mana engine, giving you flexibility against their varied lock pieces. Sphere of Resistance already punishes their heavy reliance on cheap cantrips like Impulse and Gush, and Swords to Plowshares remains fine since they have no real creatures to worry about beyond incidental threats. Land destruction is less impactful here since this deck is already land-light and mana-hungry by design, and destroying one land rarely undoes the advantage Stasis provides, so trim Winter's Grasp and one Thermokarst for the artifact and enchantment hate. Keep Oath of Druids in as your primary win condition, since it can generate a huge threat while they are tapped out maintaining Stasis.
