I was leveling two in parallel: Valk and Vidomina. The first became an Air expert with a chain, the second - an Earth expert with КЗ and permanent 400 mana (there were three Dungeon villages), which gave me powerful control in terms of transporting troops and clearing around captured Castles.
Quickly built up the far native secondary town, took two Dragon Utopias, bought a lot of meat, attacked..

Intercepted Tazar on the move; out of 5 angels on mass haste, I killed only two (!!! Crashed in with my own 5, 18 vamps, 150 archers, 18 horses) - so when the opp paid off, I wasn't even particularly happy, but the opponent suddenly decided to surrender.
Thanks for the game!
