Favorites, to battle! - 9 - The Battle of Favorites! - 9

My opponent had a castle right next to my castle, guarding a quest artifact worth 35 gold per turn from ogres (according to the judge, it was 24). He lost a lot of troops there (according to the judge, he was fighting and losing units one by one). I had 6 towns, 3 heroes focused on income, an income of around 4k, double income, a stash of air units, and on turn 116, my air units were ready to attack, but my opponent surrendered.
