BLITZ TOURNAMENT

I'm asking in advance, I haven't tested it thoroughly yet. There are 18 of them in total, and if I dismiss 12, I'll be left with 6 options, but I'll need 7 or 8 heroes, what should I do then???

Well, as an option, after you hire the last possible hero and he completes his turn, you can save and send your save file to the host... That will be your result... And what ELSE can be done here without violating the rules? Only optimize movement to have enough heroes... And we all already know how to do that... :)
