Deck looks nice.
I, however, miss a couple of good artifact cards:


* Blinkmoth Urn : More mana withour extra cost
* Arcbound Crusher : More artifacts come in play, the stronger he gets.
                  AND he has modular: he dies, the counters move to another creature you control
* Mirrorworks : Make cheap copies of your artifacts
* Rings of Rebirth : Copie the abilities for only 2 mana
* Soul foundry : Imprint a creature and play this creature every turn
* Unwinding clock : Untap all your artifacts during your opponents turn
* Heartstone : Make your creature abilities 1 mana cheaper
* Karn, Silver Golem : When mycosynth lattice in play, destroy your opponents lands for 1 mana a piece




I would also consider to take Mirrodin's Core out of the deck.
Because you have only 1 color, he's not that great.
I believe that an island would give you more options.
