Awesome Artifacts [WiP, 3-1 FNM record] (Standard)

Still fine-tweaking it a bit.

The biggest issue is it's overly reliant on Steel Overseer to the point it's nearly a Leyline situation where you might consider a mulligan without it. Furthermore, take extra precaution to keep a copy on the board for as long as possible. One way of doing this is to bait out the opp's direct removal with other creatures first. Plus, Steel Overseer works better with a flooded board, so I'm not in a hurry to get it out on turn-2.

The deck is also quite slow, so keep that in mind when side-boarding if you need additional speed. I hope to rough out its inconsistencies in this regard later.

Brewing this deck was very difficult because you're in a bit of a balancing act between artifact creatures, artifact non-creatures, and non-artifacts. For each artifact non-creature, you're depriving the deck of a potential target for Steel Overseer; however, there's not enough good artifact creatures to form a complete deck, so utility artifacts are still a must-have. For each non-artifact card (ex. Flux Channeler), you're depriving ammo for Karn's Constructs and Sai's etb triggers. Even now, I'm not convinced I have this ratio perfect.
