Boros Moxite leans heavily on artifacts for its mana and value (Melded Moxite, Lembas, Ragged Short Spear, and the artifact-land cycle), so all three Steel Sabotage come in to counter or bounce these key pieces and disrupt their curve. Bouncing an artifact land or countering Melded Moxite's card-draw trigger is a real tempo and card-advantage swing. Trim the slower Meeting of Minds and one Negate, since proactive artifact disruption matters more here than incremental card draw against their efficient curve of Kor Skyfisher, Glint Hawk, and Dispatch. Sunscape Familiar and God-Pharaoh's Faithful continue holding the ground against their small, aggressive bodies.
