Okay, cuts.

I would cut On Serra's Wings. As fun a card as it is, I'm not sure a four mana aura that doesn't recur itself somehow is going to be worth it in this deck.

Teshar, Ancestor’s Apostle Only hits fifteen cards in your deck. Still probably good enough. I'd say you NEED to add a Mother of Runes to this deck though.

As much as I love Conqueror's Galleon  ^Flip, it is isn't a great card. It's probably among the worst 9 in the deck if you are looking for 9 cuts.

I've never been a big fan of Sword of Vengeance. That and Forebear's Blade could be easy cust to get the other actual swords into the deck if desired.

Skysovereign, Consul Flagship is a sweet vehicle but it costs 5 and is probably not good enoug here.

Grappling Hook and Inquisitor's Flail are equipment that always seem sweet in theory but haven't quite put the work in for me, and I've often ended up cutting them.

I think Ghostfire Blade is the worst of your 1-mana equipment and could be cut.

I always try to put Masterwork of Ingenuity into my decks and it always ends up getting cut. Maybe you will have more luck, but its such an easy thing to cut when looking for things to cut because it doesn't do anything on its own. It's probably better here than in most decks though, with the 1 mana draw a card attached.

I'd cut Key to the City since it doesn't draw you cards. If you want more ways to make Sram unblockable there are more equipments/auras that can do that (and Mother of Runes would help).

No Argentum Armor? I know it is very expensive for this deck's curve, but I still think it may be worth it. It's a very powerful equipment and you are a tad light on removal anyway.

I could go either way on the creatures that just get boosted for being equipped like Kor Duelist, Auriok Edgewright, etc. If your plan is to do Voltron with Sram, they really don't help you toward that goal in any way and could be easily cut. But they are not a bad back-up plan if you don't want to go all in on Sram voltron. Hmm. Similarly, is Mirran Crusader doing anything special here, or is he just a fun dude to equip?

Am I missing why you would run Second Sunrise over Faith's Reward? The prior helping out all your opponents seems like a bit much.

Auriok Steelshaper doesn't do as much as he sounds like he might and I have cut him before. Sram isn't even a Soldier/Knight to boot. Same with Stone Haven Outfitter; remember that if you are doing Voltron and equipping Sram and he dies and you put him in the command zone, he didn't die so you won't draw a card.

So all that said, I would suggest the following:

IN: Argentum Armor, Mother of Runes, Sword of Fire and Ice, Sword of Light and Shadow, Faith's Reward

OUT: Second Sunrise, Forebear's Blade, Sword of Vengeance, Key to the City, Skysovereign, Consul Flagship, Masterwork of Ingenuity, Ghostfire Blade, Grappling Hook, Inquisitor's Flail, Conqueror's Galleon  ^Flip, On Serra's Wings, Auriok Steelshaper, Stone Haven Outfitter, Mirran Crusader

That should bring tyou from 109 -> 114 -> 100, if I did my math right. Oh, and you definately want Field of Ruin/Tectonic Edge/Ghost Quarter/Strip Mine with this kind of deck! Otherwise Maze of Iths just ruin your whole day. And Rogue's Passage.

Good luck!
