After all the restarts, it turned out quite poorly. A Dragon Fly Hive on 6 Wyvern taken from under shifted guards helped me get rolling. At the start of the third [month/week], I revealed the Cartographer, but realized it could only be used at 142 :smile35: In the meantime, I gathered a fair amount of resources, without leveling Diplomacy on anyone or finding it in the University and 4-6 huts, a few parameters, and 4 Death Knights. With 15 Angels, 40 ducks, and 700 Skeletons, I jumped toward the opponent and overwhelmed him during his expansion.
Thanks for the game.

P.S. It wouldn't be a bad idea to make the hero list in alphabetical order rather than random.
