The game was going evenly, but on turn 121 I didn't manage to pass the horses and reach the computer's castle in time. The computer upgraded, came out of the tower with upgraded troops, and killed my entire army..

There was an encounter with roughly equal armies in the middle of the second week; both had a power spike, but I retreated due to having less mana and went to clear the neighboring respawn. The respawn turned out to be Castle-aligned, with caches and consulates. In the end, it led to nearly 800 skeletons and 13 angels by turn 136, and victory.
