Right now, this can draw pretty consistently straight flushes (7 to J) or fives of a kind. Decimator Arrays are not absolutely needed for SF as long as you have a decent stud/draw bonus (2s/2d works wonders). Comin' Up Roses also helps if you happen to have it in hand.
Must remember not to get into shootouts too early, though. Be patient, get those decimators, give one to Joseph, give him a spell or two, summon Ancient Spirits and affix their souls to chunks of metal to make your Wretched army!
