So, having checked the beta rules, Im gonna borrow a line from Spoony: "The game is unbalanced trash. But, whats important is context, and in this case its a party game. An at parties, people do many things and it includes getting drunk"
So, basically like I called its a point based game, targets are shuffled and then drawn at random, you can use magic cards or IMP-terruption cards (someone kill me) to screw over other players, theres also summon cards which gets you various characters from the show, each card having their own thing that gives a quick resolve. Game ends after 5 rounds as basically portal closes or if all targets were snuffed out and players calculate who got more points.
