You've got the basics.
There are really 2 kinds of builds, and they dont really work great with models combined.
Molly is great as a henchmen in either build.
Belle based. Pretty self explanatory.
combination of Belles, Doxies, and a Crooked Man or two as Lure works great with Shafted.
Fear based. Not to be used against crews that are immune to morale duels.
Molly, Hanged. Yin. (crooligans if desired)
This build is all about debuffing WP a silly amount, and springing mass auras which send the models fleeing.
Worst case, your opponent has to burn their entire hand cheating the morale duels.
I love Bette and try to include her whenever possible.... worth the 9 SS but not a must include.
