That's how it was!
I decided to mess with his nerves and gave him a Necromancer as an opponent. It backfired on me :) But the game turned out to be exciting, and even though I played almost flawlessly (except for the mistake when I didn't have enough money to place a Grand Magus at the end and replenish mana), 600 gold worth of skeletons with artifacts +1 to speed and +1 to health were difficult to stop in the third week.
Thanks for the game!
