“Two Seasons: Winter-Spring 2016” Tournament. Online games for rating (reports, discussions).

Before I could even blink, my castles were pushed back, and then Kirr, with slightly lower combat stats, decimated Gurnisson's army with an implosion spell; I barely managed to buy myself some time with the remaining troops.
However, Gurnisson had a trump card in his backpack, and on the last turn, he reached the village where Kirr was stationed and launched a counterattack. The cannon hit hard, and Kirr raised the white flag.

Thanks for the interesting game!
