Needs more testing but the idea is to be a self sustainable frontline / medic, with cards like charitable soul and the combo combat knife + battle lust. I pick shell carrier and scattergun skills so you are not completely useless against riddens and you can deal decent damage with a shotgun.
You are supposed to play Mom for that extra support inventory slot, but Doc is as good if not better (maybe swap field surgeon for shoulder bag if you wanna Doc).
