Stoneforge Masterwork looks to be especially synergistic since you're constantly pumping out Cat tokens every turn. It's also cheap to play and equip.

Argentum Armor ought to be included for its high power level; you've got so many ways to cheat equip costs anyway that it might not be an issue.

Sword of Vengeance is a nice package of all things keyword. So many of the abilities are relevant that it's worth a spot.

Steelshaper's Gift is the original Open the Armory that is even more streamlined for your build.

Great decklist!

Eight-and-a-Half-Tails is a better purely Voltron commander. If you stick with the Kemba plan, you might add something like Coat of Arms for payoff with the cat tokens.

Lightning Greaves makes all of the other equipment fall off (Swiftfoot Boots do not suffer from this issue) so you should probably remove it. Use stuff like Mother of Runes and the aforementioned Eight-and-a-Half Tails to protect Kemba instead.

You've overloaded on board wipes when ostensibly a big part of your gameplan involves flooding the board with tokens. You should run a few, but maybe consider removing some of them your spot removal such as Swords to Plowshares, Path to Exile, Council's Judgment and Oblivion Ring, which is both versatile and something you can tutor for if you absolutely have to.

Also, Steelshaper's Gift.

I don't know how I feel about Renounce the Guilds... You could probably take it out for Konda's Banner, which pulls double duty in making cats and pumping cats.

Actually, Lightning Greaves doesn't remove other equipment if it becomes attached. You can't target with any more equipment, but it doesn't remove equipment already attached. Just be careful to attach the Greaves last and you'll be fine.
