The key to winning with Ulm is keeping a steady supply of Kässpätzle and Schupfnudeln. Honestly.
Personally, I prefer large amounts of contructs (Mechanical Men, Crusher, etc) backed up by blade-wind casting mages. Add to that some cavalry and you're good. And forge as many items as possible.
Then, of course, I'm not exactly an expert in Dom2.
