Steel Sabotage is premium here, countering their key artifact spells like Myr Enforcer, Refurbished Familiar, or Utrom Monitor, or bouncing an already-resolved threat back to hand to reset their affinity cost reduction. Hydroblast picks off Galvanic Blast or any red permanent they commit to the board. We trim our weakest tempo creatures since this matchup is a race where efficient interaction against their cheap threats matters more than incremental card advantage. Prioritize countering their artifact-cost-reduction engine pieces early before they can flood the board cheaply.
