I have at least 2 decks of every possible color combination, except for colorless, which I had none. So I was trying to think of a unique colorless deck, that doesn't fall into the usual Darksteel Forge / Nevinyrral's Disk / Infinite Mana type stuff. Nothing against it, it's very effective; it just seems like a lot of colorless decks use the same tricks, and I wanted something different.
So I hit upon doing a "Peasant" deck (commons and uncommons only), playing an unusual uncommon creature as my general. I got it down to either this, or doing a Brass Herald tribal Golems (or Constructs) deck, that bounced Brass Herald repeatedly somehow.
I know that Peasant is usually has a limit on the uncommons (like 6 or 10), but I thought that with the deck's limitations it would be weak enough to be OK. There aren't a lot of playable artifact commons; doing pure Pauper seems really difficult.
Tons of mana ramp and card draw (well, what card draw there is at the common/uncommon artifact level)
Infect creatures, Huge creatures (to pump/haste/fly with Golem Artisan)
Equipment that adds unblockable
