Well the previous deck I posted is just way to slow. Killing on turn 5 usually. Berserk seems to benefit the new Goblin/Sligh type build more then a R/G hybrid.
Here's what I've been testing now. Perfect draw you can kill on turn 2. 3-4 is much more common then with the R/G. This is technically R/G but really your only splashing Green to get the Berserk. Piledriver is flat out insane with a couple pals and Berserk

2 Lightning Blast
1 Mox Ruby
1 Black Lotus
4 Mountain
4 Karplusan Forest
4 Taiga
4 Wooded Foothills
4 Chain Lightning
4 Lightning Bolt
4 Berserk
4 Reckless Charge
4 Raging Goblin
4 Goblin Goon
4 Mogg Flunkies
4 Mogg Fanatic
4 Goblin Lackey
4 Goblin Piledriver
I'll mess around with this a while more and then see what I can come up with for Stompy. Problem is the lack of haste slows the kills down some. Might play around with Invigorate some though (If you control a Forest you can have target opponent gain 4 life instead of paying it's casting cost) since it would net you 5 damage with a Berserk for only 1 mana. Not as efficient as Giant Growth (net 6 damage) but it does use less mana so it's potentially quicker.
