But regarding the map "Everyone is Fighting!", an idea occurred to me. When Syre gained Air Magic at level 2, I thought that before starting the game, you should check all heroes with 30 mana to see if they also gain Air Magic immediately at level 2. Choose 2 or 1, if there aren't 2 available :). And then, with 3 or 4 air mages and 2 air units, the map should be easy to complete in 7 days.
For now, I recommend familiarizing yourself with the Tournaments rules
