This is showderp, where a person dubbed champ is forced to summon six demons that we suggest to him, so that he can force his way through Showdown and create either a world of chaos or order. Or if he's a pussy, he can just choose the middleground.
If champ runs out of MAG, he calls "new team" to replenish his stock of demons. If champ dies and doesn't want to leave the river styx for the 50th time, though, he calls new champ to pass the mantle off to another.
