So I'm currently running this goblin deck and I was wondering of anybody had any suggestions to improve it.
I tried adding grapeshot but I wasn't hugely impressed with the damage I got out of it.

Goblinstorm! Seems like a lot of the deck doesn't do all that much if you don't draw Empty the Warrens, and there's a risk of emptying your hand to play the bigger stuff like SGC before you get to Empty - are you hoping to be all-in on the storm plan, or are you going for a balance of combo/aggro?
