Thank you for all the feedback.  Tonight I went ahead and picked up a play set of Ornithopter to replace Archbound Worker.  I also had a time to do a few test runs and the deck does seem to play slower than I'd like but tends to dominate if the game is allowed to draw on.  I definitely need to speed it up a bit.  I had 2xThrone of Geth sideboarded but I plan on tossing it in on the next run.  I also really like the Jinxed Idol and Blasting Station ideas as well.  I originally had tried both Pentavus and Thopter Assembly in place of Myr Battlesphere but neither seemed to have quite as much impact as the battlesphere.  I have also considered Salvage Titan but it is currently sideboarded.  Thank you again for all of the feedback, you have given me a lot of food for thought.  Also, can you remind me on which lands are used in the cookie cutter Affinity decks?  Those may be my next bigger trade investments.

I'm familiar with affinity but unfortunately I don't have many affinity cards.  I was also looking to build something that was maybe slightly different than the usual for people to play against.  This deck will mostly see casual game play but I will probably try it at a few FNM tournaments as well.

So the goal of this deck is to make a bunch of Myr tokens with Genesis Chamber or Myr Turbine to either feed one of my sac engines (Bubbling Cauldron, Trading Post, or my lone Arcbound Ravager) to deal damage with Disciple of the VaultArcbound Crusher is my second win condition since he gets freaking huge fast with all of the tokens entering the battlefield and can swing for a lot with trample.  I included a play set of Dross Scorpion so that I can untap my artifacts whenever another artifact dies which will then allow me to sac more tokens or make more myrs.

I've just assembled my first modern deck.  Anyone have suggestions?  Also, I still need a sideboard..

Hi all!  I would appreciate any feedback I can get on my deck.  Some of my initial thoughts are that Righteous Authority, Imposing Sovereign, and Artisan of Forms should probably come out.  There are probably better options than Stolen Identity as well, but so far I've enjoyed being able to make copies while triggering heroic multiple times with the cipher.
