Whenever Armix attacks, you may discard a card. When you do, target creature defending player controls gets -X/-X until end of turn, where X is the number of artifacts you control plus the number of artifact cards in your graveyard.
Partner (You can have two commanders if both have partner.)
Build a critical mass of artifacts so Armix's attack trigger becomes a repeatable removal cannon, discarding a card to shrink (and usually kill) any blocker or threat the defending player controls. You ramp into cheap artifacts early, fill the graveyard, and use Partner to add a second strategic angle while Armix grinds the board down to nothing.
Add fast artifact mana (Sol Ring, Mana Vault, Mox Opal) and zero-cost artifacts to spike Armix's X by turn three or four. Lean into a sacrifice/recursion engine (Krark-Clan Ironworks, Scrap Trawler, Trading Post) so artifacts in the yard keep counting and rebuild after wipes. Choose a Partner like Tymna the Weaver or Akiri/Bruse Tarl to add card draw, evasion, or a second color that unlocks Disciple of the Vault and Reckless Fireweaver finishers.
