The problem here is that the stuff that's good with Loam - extra lands, Mox Diamond, Dark Confidant, Crusher, Assault - is either too slow or actively detrimental in a matchup where your sole goal is to do as much damage as quickly as possible. Unfortunately, so much of your deck is dedicated to making Loam work that you can't sideboard that stuff out in favor of anti-combo cards and expect to win, not unless you want literally your entire sideboard to be fast aggro cards and discard. It's often best to just accept that you can gain a couple of percentage points in games two and three with some token discard, but it will basically never be close to positive for you.
EDIT: If you want to stay GB/x, where x is not blue, I'd suggest a Maverick base with a black splash for Bob, Abrupt Decay, Thoughtseize, and Inquisition. Thalia, Teeg, and the discard should put the hurt on combo and you'll have enough creatures to back that up with a credible clock.
