This is an artifact/token deck I have constructed from a combination of affordable cards I found online and cards I had readily available.

Tempered Steel is worth considering.

Ya, I agree it could be useful. I use that card in other artifact heavy decks. The reason I didn't select it for this deck was because I had Myr Galvanizer x4 and Obelisk of Urd x2, so I thought it would be a bit too much focus on beefing up my Myrs and not enough focus on producing them. I prefer Obelisk of Urd over Tempered Steel for this deck despite it's 6 CMC versus Tempered Steel's 3 because: Obelisk of Urd is purely colorless, reducing the (slightly) restrictive need for two plains, it can benefit from convoke to further reduce mana cost, and it can be brought back with Reconstruction.
