Need:
$$$ Commander's Plate

Maybe:
* Thieving Skydiver - Take someone else's equipment, or just a Sol Ring
** Urza - Tap equipments for mana! But currently used in Breya
* Sword of the Animist - Ramp, but probably not as good as in UW Ardenn
* Colossus Hammer - Hard to get more stats for such a low cost, assuming I can keep Ardenn or similar around for cheating the equip cost
Masterwork of Ingenuity - Copy the best equipment for cheap
Mask of Griselbrand - Evasion, lifelink, and card draw should my dude get removed
Goggles of Night - Cheap equipment that scries and draws every turn
* Dispatch - Great removal, although I should probably play Swords before this
* Reshape
Swords to Plowshares - Efficient removal
Sword of the Meek + Thopter Foundry - Thopter Foundry to sac artifacts to make sure Silas has something to return is nice, and if I'm playing that I should have the combo
Reality Heist - Dig for more equipment
Ugin, the Ineffable - Discount and card advantage
Despark - Cheap removal
Grafted Exoskeleton
All that Glitters - Big pump for cheap
Prowler's Helm - Cheap unblockability
Taj-Nar Swordsmith - Tutor an equipment straight to the board
Krark-Clan Ironworks - Sacrifice stuff to go up the chain, then recast it later with Silas. Not sure I have enough disposable stuff though
Clock of Omens - Get pseudo-vigilance by tapping equipment to untap
Masterful Replication - Turn all my equipment into a cool one after blocks, but only works if equipped to a non-artifact creature
Mirrormade - Copy whatever artifact or enchantment is best, but it doesn't synergize with my tutors, card draw etc, and 3 cmc might be a bit much
Trailblazer's Boots - Cheap unblockable equipment
Ornithopter of Paradise - Mana dork that is evasive for when I just need someone to hold equipment
Chrome Courier - Cheap flier that can "draw" up to two cards (if I hit two artifacts and have Silas able to connect)
Open the Vault, Dance of the Manse - Get back multiple equipments in one go, but they are pretty expensive to use. Maybe Silas' ability is enough
Fleetfeather Sandals - Haste and evasion
Stubborn Denial - Hard counter as long as something is suited up, but it probably won't help me get there in most cases
Mechanized Production - Get copies of cool equipments, but putting this on good equipment means opponents are more likely to destroy them before I even get a copy
Vorpal Sword - Alternate win con against high life totals
Trinket Mage - Shadowspear is sweet, and this can get Altar of the Brood if I have the rest of the Sharuum combo
Spellskite - Protect a suited up guy from removal, but can only do it once. Maybe more useful if I use it to retarget Ardenn trigger, then equip to something else next turn, but that requires the opponent's removal to be timed correctly
Vedalken Archmage - Draw cards for every equipment I cast, but with 3+ drops I probably won't get many of these per turn, and a 0/2 for 4 isn't great
Sword of Vengeance - First strike and trample for making blocking hard, vigilance for making attacking hard, and haste for the surprise (probably want to play if I have it)
Sydri - Turn my equipment into creatures if necessary, or give Silas deathtouch and lifelink
Umezawa's Jitte - Probably not as good in EDH
Liquimetal Torque - Cheap rock that can let me sac non-artifacts to Fiddlebender etc
Talisman of Hierarchy - 2-mana ramp, but can't find it
Cloudsteel Kirin - Platinum Angel effect on an equipment that can also be a body if necessary (but without the effect)

Checklands (Glacial Fortress/Isolated Chapel/Drowned Catacomb) - More untapped duals
Inventors' Fair - Tutor for what I need. Currently in Breya, but this deck tolerates colorless lands better
Reliquary Tower - I can probably draw a lot of cards, but with Silas I might have higher tolerance for discarding artifacts
Inkmoth Nexus - Can probably often kill a player after a sweeper by just playing Ardenn
Eiganjo, Seat of the Empire - Land that can be used as removal
Obscura Storefront - Can get whichever color I'm missing, and gain a life, but enters tapped
Seachrome Coast/Concealed Courtyard - Early untapped white duals
Bouncelands?
Power Depot - Artifact triland for artifacts, with modular 1 as an extra bonus

Maybe (don't have):
Mask of the Schemer - Can easily dig pretty deep, and grow the dude to scary sizes
Sanctuary Blade - Cheap equipment that can give protection from the color I need to sneak through
Mystery Key - Draw 3 cards every two turns when Silas attacks
$$ Slowlands - Mostly-untapped duals
$$ Cloud Key - More discounting
$$ Artificer Class - Discount, draw and copied equipments!
Armored Skyhunter - Flier that can draw an equipment and put it straight onto a creature every combat
$$$ Hammer of Nazahn
$$ Robe of Stars - Protect my equipment
$ Leonin Shikari - Instant equips
$ Mantle of the Ancients - Get back a bunch of equipment from the yard straight onto a guy
Relic Seeker - A cheap body that can tutor another equipment the first time it connects
Anchor to Reality - Tutor an equipment straight to the board
Glacian - Use equipments to dig
Open the Armory - Cheap tutor for an equipment
Kemba, Kha Regent - Go wide while going tall
Fumble - Move all equipment from a blocked to an unblocked creature, or just steal someone else's strong equipment
$$ Halvar, God of Battle
$$ Balan, Wandering Knight
Replication Specialist - Flier that lets me copy artifacts
$$ Sword of Sinew and Steel
$$ Sword of War and Peace - Risky because it gives protection from Ardenn
$$ Wand of Orcus - Get a bunch of zombies
Vault Skirge - Nice body for carrying equipments
$ Pact Weapon - Card draw, pump and loss prevention
$$ Kappa Cannoneer
$$ Akroma's Will
$ Tezzeret, Betrayer of Flesh - Discount the first equip each turn if I can't have Ardenn, draw cards or worst case loot with the plus, and it might even be allowed to live to an ult, letting me draw a ton of cards when I have ways to tap my equipment
$$ Sevinne's Reclamation
Blade of the Oni - Cheap body that can be an equipment when I have something else to carry it
Ironsoul Enforcer - When a commander is suited up and attacks alone, I get to reanimate an equipment
Slash the Ranks - Sweeper that leaves my two commanders alive
Draugr's Helm - Equipment with evasion and pump, as well as the ability to get a body for it
Whispersteel Dagger - Cheap equipment that can get me some bodies

--------------

Considered cuts:
Sai - Do the thopters do much for me? Also not sure whether I need the sac ability
Scrap Trawler
Champion's Helm

----------

Cuts:
Sword of Light and Shadow - The trigger is super underwhelming, and the pro white means the equipped creature can't be targeted by Ardenn's ability. Could be put on Ardenn to protect against most spot removal, though
Disciple of the Vault - Pay-off for the Sharuum combo, but also a cheap body that can carry equipment. However I have no way to tutor or recur it, so it's risky to play early
Dauthi Voidwalker - BB is hard, but other than that I really want to play this
Infiltration Lens - Disincentivizes blocking, but
Altar of the Brood - A tutorable way to end the game with Sharuum + Sculpting Steel, but does nothing else for the deck
Sharuum - Might be a bit expensive if I end up cutting the combo payoffs
