Round it down to 60 cards, replace something with Mycosynth Golem, add Shapers Steel and Mycosinth Lattice, remove the Arcbound Bruisers and add Seat of Synod. Some more Vedalken could be useful, and adding cards like Energy Chamber could be useful for Aether Vial. Coretapper as well could speed up the usage of Aether Vial, and consider that even with no Charge counters on it, you can still put an Ornithopter or a Phyrexian Walker into play on your opponents turns.

Even then, I also advise that you add cards like Cloud Key to speed up the general process of getting out artifacts. Blinkmoth Infusion could also be a choice card. Please look at my deck Lotus Queen and tell me what you think of it.
