This deck focuses on a weird combo involving Mishra, Artificer Prodigy and Esperzoa. By bouncing (via esperzoa) some of the cheap artifacts like Ornithopter and Energy Chamber, along with the Etherium Sculptor I can easily play multiples of any given artifact, pumping up the glaze fiends along the way.
With one Esperzoa and Mishra, Artificer Prodigy, for instance, I can return an Energy Chamber to my hand (after already placing its counter on the Glaze Fiend), play it, search for another copy and put it in play, making my glaze fiend a 5/6, for two mana that turn. On top of that I can drop an artifact land, any 0 cost artifacts and search for copies of them. He gets scary quick.
Sculpting Steel becomes even more powerful with the Esperzoa, because now it's no longer stuck as a copy of the original target, I can bounce it and literally recast it as something else. An Etched Champion, an Energy Chamber, a Glaze Fiend, whatever I need at the moment.
Lotus Petals are the newest addition, they make the deck ridiculous. By playing one from my hand, using it, then dropping another and using Mishra's ability to play the first one from the graveyard gives me excellent mana ramp and pumps the Glaze Fiends like crazy.
I use the Lightning Greaves mostly to protect Mishra, Artificer Prodigy and my Glaze Fiends, though giving them haste along the way isn't bad either (I frequently forget Mishra has 4 power himself). The deck is based on having four of each artifact, to maximize his effectiveness. I'm considering completing the set of Lightning Greaves, but I'm already at 64 cards and the deck works pretty well as it is.
Open to suggestions for improvement!
