I've toyed around with the following SB:
1 Volcanic
1 Badlands
3 Pyroblast
2 Firesprout
3 T.Crypt
3 Hydroblast
2 Krosan Grip
I'am not sure bout it, but red proved itself quite solid in a few test games vs. VG and vs. CB-Decks (Supreme U & Dreadstill).
I've also thought bout playing one of the duals in the maindeck, to be able to play the third Sprout.
