Desolation Row- Shoot'em Out

My attempt at a shootout deck. I'm going for a straight flush in a shoot out; might also get 4 of a kind as well. My first attempt had some goods (Peacemaker, Shotgun, and Pair of Six Shooters) but they didn't really add much. I also had had about 22 clubs which was way too low and I was always short of getting a decent hand. Haven't tested this deck yet, I'll be playing it tomorrow with a group for fun. Would definitely love some advice and suggestions!
