If you are playing equipments and a lot of tokens, Sigil of Valor should be powerful enough. Or Golem-Skin Gauntlets

Personally I also like Godsend

Things like Relic Seeker or Steelshaper's Gift could be good to get your best equipments.

I don't know your budget or if you want to make the deck really competitive, but these are my thoughts. I would remove ramroller, veteran armorsmith (there is only 2 other soldiers) , and maybe even radiant fountain. Maybe add some equipement with lifelink like Loxodon Warhammer if you really need lifegain.

I get what I can, when I can. College life can only get you so many cards, unfortunately. Relic Seeker is a good replacement for Veteran Armorsmith and maybe I can replace Ramroller with Isamaru, Hound of Konda for early damage or another Defender like Wall of Omens. Ramroller seemed like a funny idea to play around with in an equipment deck when it gets the damage boost from other Artifacts and wrecks the field. Or using that extra space left from Ramroller is good to stick in Loxodon Warhammer.

As for lands? I dunno, Drifting Meadow? More or less using what I got from the box that's begging to be liquidated for better cards. I'm not looking to get super competitive with it, as playing for me is more on the social aspect. But winning sure is dandy!

Drifting Meadow is a good idea. If you draw too many lands you can switch it for another card. And because your deck is only white, I don't think Evolving Wilds and Terramorphic Expanse are useful. They will only get you a basic Lands. I would trade them for 2 Plains.

Big defensive creatures are a good idea to defend yourself while your main creature is not on the battlefield. But if you can find similar creatures without defender, they could also be targets for equipments and could attack. Or maybe get more tokens producer (something to spend your extra mana if you don't have anything to play). Shrine of Loyal Legions - Ajani, Caller of the Pride - Spirit Bonds.

Most of the time a token could block anything that Guardians of Meletis could block. You can also add Gorgon's Head or Basilisk Collar and keep a token blocking to prevent some attacks.

Finally, evasion abilities like Fleetfeather Sandals - Bladed Pinions - Prowler's Helm - Chariot of Victory will really help you do some damage to the opponents.

Maybe add more removal if you can.

Maybe Ensouled Scimitar - Slagwurm Armor could also interest you.

Slagwurm Armor is an excellent turn one for big defense in place of Accorder's Shield. However, the latter has vigilance, which won me a game against Cosmic Larva with Lightning Greaves.

You need asap a Basilisk Collar, and some swords (Sword of Feast and Famine,Sword of Body and Mind... etc...) I'd also use a Darksteel Plate, those are the equipments I usually use in my commander to keep Narset alive, and in my tiny Kemba, to wreck everyone else...

You may want to exchange a wall for a kitty that gives you the ability to equip anytime you could play an instant. Also, get rid of Veteran's Sidearm its pretty much useless, get some Lightning Greaves or the much cheaper Swiftfoot Boots.

Lands,

You have a big problem in there, you want to get as much as you can from Strata Scythe but, you have 8 LANDS that aren't plains, and some of then do not give you utility, the lighthouse is ok, but Ghost Quarter, Myriad landscape, Foundry of the consuls, are not the kind of lands you want in a fast paced game as tiny leaders.

You may even switch them for plains and you'd probably be ok, now, Karoo and Emeria, The Sky Ruin would be good substitutes for those as well (If you bought the "Forged in Stone" 2014 Commander I'm sure you have them). Also think about lands that enter tapped, they are not giving you utility, nor helping you out to get your shiny gear and stomp your opponent, therefore I'd switch Myriad, Secluded, and Mistveil for plains, in a monocolored deck, you only want really really good lands to be fast or have utility, or basic lands.

Plains are your friends.

Sorry for my awful english (4 am, and looking at decks... kill me), and I really hope you can improve this deck, and wreck them all with the Mighty kitty blink blink, that calls kittys.

Oh yeah the kitty that lets you equip as instant is Leonin Shikari I do not own her, but I'm sure I'd be an asset in every equipment deck (but Narset's.... )
