I would highly recommend Slop Haulers and if you want to make a summoning Somer list, then another box of Bayou Gremlins. But you can work with just the two boxes just fine for a start. For upgrades, I always take Liquid Bravery for my leader though if you have no Slop Haulers you might choose to leave it home since you probably won't be using the (0)Action. For Francois, Stilts are golden since he is super killy but rather squishy. They can also be used to mitigate the damage he takes from his Dumb Luck trigger. For Raphael, Dirty Cheater is golden as it can make him super hard to kill taking him above the Hard to Kill threshold repeatedly. The other Dirty Cheater should go on Ophelia or Francois - if you have no Slop Haulers, then I would choose Ophelia.
