I played very poorly, but the double build and a tasty treasure zone allowed me to win.
Week 1. Native secondary skills 1-5 in the Citadel in the main, secondary hero 1-3,5 in the Citadel.
Week 2. Secondary hero connects, 1-5,7 in the Castle, in the secondary hero with the same (well, and tithes and markets everywhere).
Then I run to the treasure zone, on 142 I take a minimal Dragon Utopia (+6 to all, shield +3/3), then a cap of 5 after the horde of upgraded Liches (nearly a hundred). Through ГО, I take the Castle, I see the opponent's hero in the treasure zone. Back home, I catch a noob with a strong army (Valya on Angels) and ГГ.
Thanks for the game!
