Giving up to luck! All restarts were used, and it turned out that I had a decent-sized zone, while my opponent had a tiny one. Until the beginning of the second week, we were evenly matched (both took secondary heroes), but I had a zone with cons. I take a level 1 hero, and then my opponent takes a scout and sees my angel, after which he concedes before the angel can attack and types "gg".
Thanks for the game!
