Steel Sabotage disrupts their sacrifice-value engine by countering or bouncing key artifacts like Ichor Wellspring, Lembas, and Nihil Spellbomb before they generate card advantage, and can also bounce Refurbished Familiar. Remove Soul stops Refurbished Familiar or Gixian Infiltrator from resolving outright. Prohibit and two Negate come out since this is a grindy creature-and-artifact deck where countering their sorceries like Cleansing Wildfire is less impactful than answering their recurring threats, even though Cleansing Wildfire does not dodge Prohibit's mana-value cap. Focus on using your card-draw engine (Mulldrifter, Meeting of Minds, Lorien Revealed) to out-grind their incremental value plan while Steel Sabotage denies key artifact triggers.
