Did you find your land count too high? I like your list btw, simple and eficient.

Goyf Sligh has a good game against Goblins, with the steady amount of burn clearing the way for your beaters. The only way they can win against you is when they reach the late game and go Vial Ringleader, Warchief, Piledriver, Piledriver, etc. I've rarely lost to Goblins, and most of the few times I lost, it was to a Vintage FCG variant.
