Boros Moxite is another artifact-heavy aggro deck leaning on Melded Moxite, Lembas, and Ragged Short Spear, so Dust to Dust exiles two key artifacts at once and can shut off the metalcraft on their Galvanic Blast and Dispatch or blank their equipment plans. Standard Bearer soaks up their targeted removal like Dispatch or Galvanic Blast, protecting our real threats in this mirror-ish aggro race. We trim Phyrexian Walker and Ornithopter since Walker can't block Kor Skyfisher or Glint Hawk at all, Ornithopter is a weak blocker against them, and both contribute little to our own race. This matchup comes down to who curves out better, so keep the aggressive core intact.
