What did you place at nats?
I played a similar type of offense and got 8th only cause in rounds 7 and 8 i made tiny mistakes that cost me alot. But there's a few too many heroes I think. In the deck I played I had 11, and 5 enhancements. Why no hopper or HT? Why no grail, of all things? 12 FG kills our playing style, and grail is one of the main ways to rid the world of him.
I could PM you my old deck if you'd like.
