[swiftyman]

I would try something like this....

4 Goblin Guide
4 Kiln Fiend
4 Plated Geopede
4 Chandra's Spitfire
4 Lightning Bolt
4 Assault Strobe
4 Staggershock
4 Forked Bolt
3 Burst Lightning
2 Arc Trail
4 Teetering Peaks
3 Arid Mesa
3 Scalding Tarn
2 Terramorphic Expanse
11 Mountains

Sideboard would have to be adjusted to your local meta but could be something like this....
4 Perilous Myr
4 Flame Slash
3 Shatter
4 Act of Treason

If you are diligent on ebay for the fetchlands and the goblin guides you should be able to build this for less than 80 bucks.
