There's no village, so there will only be one Thief a turn. One Bishop a turn. All roads appear to lead to the Bishop golden deck. I agree that Thief is prominent here, so the only alternative to the Bishop deck that can possibly beat it is a Thief/Storyteller engine, maybe with a Hireling thrown in.
edit: peeked at the log. Interesting match, I could see it devolving into that, but I'm not 100% sure it is inevitable.
