Do you use much magic in combat? As an example, do your Ulmish master smiths use Earth Power, Blade Wind, Magma Bolts, Magma Eruption? Do youuse shortbows with Ulmish troops (they can't hurt Ulmish units through their armor)? Have you summoned Troll King's Court, Kings of Elemental Earth, Mechanical Men, Iron Dragons or Living Statues (last one fron Enliven statues)?

About scales: High order would give lots of gold, which might help you. Luck is fun, but you can't count on it, especially if you don't use Conceptual Scales mod.

Try different extremes. If you know them, you can try to use just enough of each of them to get most out of everything.
Try Oracle with Astral 5 and go for scales and castle. Try a no-magic Wyrm or Manticore, and remember that death costs nothing. Try Wyrm or Manticore with some magic for spells (pick one: fire shield; breat of winter and quickness; mistform and mirror image, iron skin and earth power (fatique removal); personal regeneration; luck, body ethereal, astral shield, astral weapon) and try to find out their limits. Try heavy-bless pretender for Jotunheim: W9 Son of Niefel or N9E4 Great Mother with fast-building castle (3 turns at max) and recruit lots of Jotun Jarls. Try summoning crazy hordes of Vine Ogres. Take high-Earth pretender and research enchantment just for Enlive Statues. Choose less Earth and go for Mechanical men/Iron Dragons. Try using uniques as combatants as early as possible.
