The first thing I did, was to dump as many artifacts/artifact creating cards as possible into my cube without them being narrow.
For example,
Thirst for Knowledge is a amazing in a deck filled with artifacts. However, it is also great in a deck with few of them too.
Galvanic Blast is the same: great even without the payoff, but busted with. Or replacing a Rabblemaster variant with a
Pia Nalaar, or a
Llanowar Elves with
Gilded Goose. Do this enough and you get to a certain density of artifacts present in your environment without trying very hard.
After that, a few choice artifact payoff cards for the themes you are already supporting in that color and you are good to go!
Take this deck for example: (super high power, sorry!)
https://cubecobra.com/cube/deck/5e27633fb34d413afc8c0fc8
It's a midrange RG deck that plays a
Goblin Welder. With
Cathartic Reunion,
Survival of the Fittest and
Sneak Attack, my top end creatures (which happen to be artifacts since we tried to include as many as possible) are likely to hit the GY. Thanks to my
Gilded Goose,
Pyrite Spellbomb and
Pia Nalaar, I have cheap artifacts to use with Welder. It fits right in alongside
Feldon of the Third Path as a value reanimation creature because we overloaded the cube with artifacts.
Then you have this deck: (still super high power, still sorry!)

Which is a slightly more aggressive RG deck that uses the some of the same cards, but no Goblin Welder. The clutch artifacts from the last list do not seem out of place even without the added synergies which was the goal.
The second piece of the puzzle is the artifact section itself.
If you have
Emry, Lurker of the Loch,
Marionette Master and
Goblin Welder as your minimalist artifact theme payoffs, then you will need a bunch of cheap and versatile artifacts that can go to the GY for value.
Mishra's Bauble,
Chromatic Star and
Terrarion, will complement your suite of
Witching Well,
Executioner's Capsule and
Pyrite Spellbomb you already have in the mono-colored sections. They are also just generally useful cards for color fixing, smoothing out draws, delirium, etc. so even a deck without the artifact payoffs will play them.
Last point I want to talk about is avoiding cards like
Sai, Master Thopterist that actually care about casting artifacts. Most of the artifact generating cards in your lists aren't artifacts, they are colored spells! You will rarely achieve the needed density of artifacts in your decks to trigger them reliably and it is a frustrating trap for your drafters (unless your colorless section is a large portion of your cube).
TL;DR
- Load up on artifacts/artifact creating cards whenever possible (Pyrite Spellbomb, Witching Well, ...)
- Load up on effects that care about artifacts, but don't need them to function (Thirst for Knowledge, Galvanic Blast, ...)
- Choose artifact payoff cards that fit into what themes you are already supporting (Marionette Master for aristocrats, Steel Overseer for counters, ...)
- Use your colorless section to boost the artifact archetypes with generically useful cards (Chromatic Star for Marionette Master, Walking Ballista for the Overseer, ...)
