I took a risk and picked Valeska while restarts were available. In the end, I got 34 archers with upgrades, Tant, and Vokial. Along the way, there was an impassable block of mages guarding an external dwelling of angels.

Almost immediately, I started necromancy, used Tant on turn 112 to take a dwarf dwelling at level 15, which got nibbled a bit, but it let me quickly level expert necromancy. Until turn 115, I was clearing the respawn and trying to amass bones, ending up with around 100. Both secondary heroes were blocked by gogs, so I waited for horses. With them, I broke into the underground, where from the lookout I spotted an external dwelling of necro-dragons. I took it the next day, but in the end, I was one move short of capturing the town.
At home, horses in the castle.

On turn 122, with the bones and horses, I take a level-two Griffin Conservatory and send Tant to the treasure zone, where Dragon Fly Hives have been revealed. In the hut, I learn Earth magic.
Then I clear the treasure zone, racking up around 20 ducks, take a +6 sword and the Cloak of Rejection — Solmyr is no threat. At home, angels in the castle.

On turn 127, I considered splitting off from the treasure zone to go home and take conservatories, but I was one move short of splitting, so I decided to stay. On turn 131, with 5 angels and 24 ducks, I take a max-level Griffin Conservatory using a scout hero, hand the army back to Tant, and head on toward the Dragon Utopia and the artifact. A couple of days later I reach it, and it's the minimum version with КЗ.

Then I take another conservatory with scout heroes deep in the respawn. On turn 134, I stand under ГО, and on turn 135, with 13 angels and 38 ducks, I take the opponent's main, followed by capitulation.

Thanks for the game!
