To be fair anything that paralyzes, ignores armor, Auto kill (Headshot, Decapitate, Mannequin Replacement, ETC), poisons or stops healing hurts Von Schill. He is resilient but not unstoppable. Try to focus more on his crew unless you have a good model that can put any of those things on Schilly Con Carne.
Minions that could help by Faction
Guild = Wardens, Nino, Executioner
Arcanist = Steamborg, Raspys Freeze Over, LSPA
Ressers = Hanged, Shikome (poison trigger), Onryo, Datsue Ba, Drowned
Neverborn = Twins, Tuco, Coppelius, Collodi (Death by a thousand cuts)
Outcasts = Ronin, Hans (Weird huh), Taelor, Pigapult, Rusty Alyce, Killjoy (Sheer brute force)
and these are just from the top of my head. Now I know that I didnt mention 10T and thats because I still dont have enough information to actually mention their answers. But Outcasts models are usually available to them
