On the first week, I built 1-6 in the castle + captured an external dwelling of efreet and 2 secondary Dungeon towns, where I built portals. On week 2, I made demons, captured the 2 Griffin Conservatories available on the respawn, 2+1. Then I took a Dragon Utopia with a Book of Earth and broke through a double GO. The center turned out to be Barbarian. I captured 3 external dwellings of behemoths there, picked up a Sword +5 to all stats, and visited the Library. Then I spotted the opponent, captured the central castle, portaled home for double mana, and sat in the center, waiting for the opponent's attack, hoping for a good stack of efreet, explosion, and other tricks from KZ. But it turned out he had a Cloak of Rejection, and his Lightning Bolt was 500 vs. my 300.
Explaining why I couldn't run around with single Sultan units: I was sitting in the castle and couldn't buy my way out or flee, and I didn't build a back door.
