Boros Moxite's removal is Lightning Bolt, Galvanic Blast, Dispatch and Makeshift Munitions, and all of it targets. Our hexproof creatures already dodge it, so the matchup is about racing their fliers (Glint Hawk, Kor Skyfisher, Sneaky Snacker) and answering the few things that do get in the way. Thraben Charm does that job. Its damage mode deals twice the number of creatures we control to target creature, which can kill a Glint Hawk or Kor Skyfisher once we have a couple of creatures out. Its enchantment mode destroys their one Makeshift Munitions, which is their only enchantment and a way to turn sacrificed artifacts and creatures into damage. Cut the two Cartouche of Solidarity for these more targeted answers, since adding incremental stats matters less than keeping their evasive blockers and racers in check. Keep Armadillo Cloak and Rancor as the core win condition: their targeted removal can't touch our hexproof creatures, so the main risk is Prismatic Strands blanking a combat step and their fliers racing us.
