So I play tested this deck against my Rubinia control deck and it went 2-1.  Not too shabby considering that I think my Rubinia deck is the better of the two.

I have to state that the first game, Rubinia never showed due to the lack of white mana, leaving Jor to ramp up nicely, gain metal craft and continue to pummel Rubinia with 8 first strike damage every turn, eventually winning by commander tap out.

The second Rubinia bounced back with an easy win, stealing Jor himself and leaving Jor's old team mates with no defense as he trounced them in his pursuaded mindset.

Last game was quite drawn out, with Jor first on the field.  Rubinia quickly arrived to once again sway the warrior but was quickly responded to with a Red Sun face blast, banashing her back to her penalty box.  Jor manage to amass a metal crafted army of small myrs, but was Arrested before he could do much damage himself.  It was the timely arrival of Karn, who, without much in my hand to exile, turned his sites on Rubinia's cataloged spells.  She did her best by giving up sorceries that would do the silver golem no good should the game restart.  Jor's legion however, had suffered no damage thus far and Rubinia was whithering under the assult of prototype portal pumping out bladed pinions for all the lowly 1/1s to share, gaining +3 from Jor, Karn was content to steal Rubinia's arcane knowledge, making sure that she would dare not show herself again, lest she be exiled. Her forces crumbled under the flying stings of the tiny artifacts.

I won't deny that there was some luck in the turn out, but as we have seen, sometimes that is all you need.  Now all I need is some other opponents...

OK so my fling combo doesnt work, because Fling does not actually target the creature.  Damn would have been nice.  Will have to find another way to do it.

I can't help but think this deck would be a great place to showcase the Precursor Golem/Fling combination, if only because it's got the golem focus and the right colors in play.  Add Conversion Chamber, Titan Forge, and Golem Artisan and you'll really be moving.  Other than that, seems a bit high-cost.  Maybe a Mycosynth Wellspring to move things along a little?  Geosurge?  Semblance Anvil?  Or you could pick up some of the spiffier little white metalcraft creatures like Auriok Edgewright and Ardent Recruit.
