[[Anointed Procession]] should really help in making more tokens and also reducing his commander tax by 2 effectively. Also I get the feeling he might be strong with some legacy or modern affinity shell to churn out small artifact creatures.

Depending on token production, [[Time Sieve]] could be a thing.

Artifact — Equipment
Equipped creature gets +1/+2.
Equip 
Whenever a 1/1 creature enters the battlefield under your control, you may return Sword of the Meek from your graveyard to the battlefield, then attach it to that creature.

[[Thopter Foundry]]

That's a favorite of mine. Add in Thopter Assembly and/or the Thopter Foundry + Sword of the Meek combo for extra spice

Artifact
, Sacrifice a nontoken artifact: Create a 1/1 blue Thopter artifact creature token with flying. You gain 1 life.

Oops, lol

Its no problem, happens all the time.
Anyway that is a good idea. As really with Chief Artificer, we got to view making tokens as sort of banking mana.
As every token equates to 
less to cast Urza.
Well artifact creature token. But yea.

[[Urza, Lord High Artificer]] because each token generated also can be used to generate blue mana.

More the merrier.

I'm also looking at [[March of the Machines]] with [[Tempered Steel]]
sharp aurora
The second is so that any 0 drops don't instantly die
sand fjord
[[Chief of the Foundry]] and [[Master of Etherium]]
sharp aurora
Yep
sand fjord
Also going that route also means you got access to treasures, clues, food if they are artifact creatures.
sharp aurora
[[Eloise]] and [[Academy Manufactor]] fall on that path too.
radiant frostBOT
Legendary Creature — Human Rogue
Whenever another creature you control dies, investigate. (Create a Clue token. It's an artifact with ", Sacrifice this artifact: Draw a card.")
Whenever you sacrifice a token, surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

As an additional cost to cast this spell, you may exile any number of blue cards from your hand. This spell costs less to cast for each card exiled this way.
Up to X target creatures phase out. (While they're phased out, they're treated as though they don't exist. Each one phases in before its controller untaps during their next untap step.)
