Consider Butcher's Cleaver and Mirran Crusader . Double stirike and life link can get nuts if yours boys get big enough. And if your pockets are deep enough, Sword of Feast and Famine .

Maybe some cards that make your soldiers bigger. Field Marshal is an option. There's Honor of the Pure or Glorious Anthem too. She is a high casting cost but Captain of the Watch . Militia's Pride with any of those +1/+1 cards is really good as well. Maybe Mobilization for defense?

This deck started with equipment and Auriok Steelshaper with Loxodon Punisher . Puresteel Paladin kinda took over and Etched Champion is now the game winner... I considered some different auras and maybe splitting them with equipment, I.e. Spirit Mantle or some of the umbras with some Kor Spiritdancer .

Also, I have 4 Loxodon Warhammer so I don't really need Butcher's Cleaver ... I was considering putting in Concerted Effort and maybe Auriok Sunchaser

I may add Precinct Captain and a few Brave the Elements ... Thoughts?

Consider 4x Path to Exile . You'll want at least some way of slowing down your opponent.

Also 4x Darksteel Citadel would help a lot for metalcraft. If you can afford them, adding any of the swords in place of some of your equipment may be upgrades. There's always Batterskull too. That's probably above your curve though.

In fact, I'd do this:

Replace 4x Loxodon Warhammer with1x Sword of War and Peace 1x Sword of Fire and Ice 1x Sword of Feast and Famine 1x Sword of Light and Shadow

This gives you a toolkit , you can tutor for the one that's best against your opponent.

I +1'd the deck, liked the idea and the name, even if it's not necessarily optimal.
