Thanks for the responses. This is exactly the kind of feedback I was looking for.
I think the main offender in this kingdom is actually hermit. Hermit/Counterfeit is too neat and easy a way to get rid of your starting cards, and trashing hermit for madman does even more to help you set up the engine. What this kingdom wants is for the engine to look difficult and for big money/a slog to look tempting. So hermit is out, and some kind of junker is in. Here, I'm thinking Jester, which is normally a really unreliable curser, but gets a lot of help dealing out curses with rabble. On top of that, Farming village is super powerful here and a really automatic buy, and the two roles that it is performing here may be more interesting if split across two different cards. Mystic does neat things here with topdecking in the kingdom, but at 5 you're paying too much for it, so now vagrant is auditioning for that part. Finally, all of that makes a slog look a little too good, so a weak trasher like Island may help. This is the revision:
Provinces/Estates
Vagrant, Island, Plaza, Bureaucrat, Horse Traders, Jester, Rabble, Venture, Counterfeit, Nobles
