x-men already existed
who is Vanda? Red Witch?
As for the balance, I spent a long time working on it and changed it many times. It seems okay now, but luck still plays a major role. On the very first day, 5 mafia members could die (2 kamikazes, 2 mana users, and redirection. The shooter is unlikely to start moving). Or they might not die...
But that's what makes it interesting. + The chance of a night without any killings decreases.
