The first cuts I would make would be augury adept, kongming, serene master, serra avatar, stormscape battlemage, tidal force, famine, death grasp, tempt with immortality, and go to about 38 lands. The easiest things to add are mana rocks(gilded lotus, ravnica guild signets), and draw (phyrexian arena, recurring insight).

Thopter assembly is bad, very slow. There are a lot of better ways to do the same thing. Sharding sphinx is also slow. Cut the "enchantment artifacts," sen triplets, sphinx sovereign, whispersilk cloak, and darksteel plate. Add a couple mana rocks and go to a 37 land count. Fill in gaps with some card draw because you have little to none.
