Quite the concept. I've never seen slamball so I'm not entirely sure what we're going for here, but I have seen running man and in his first challenge he has to survive a big hockey fella on an ice area. Spoiler alert he ends up killing the guy and pissing off the hosts, but I think we can find a middle ground for the SHL. For starters let's ditch this dumb oval and make the rink shape something a bit more exciting. Perhaps a square or a circle. Less of a north/south game and more of an all over play style. I was thinking we keep the nets where they are, but maybe in each corner could be fun. Next let's add bumpers on the walls that pop out at random times. Lastly let's add a player that just stirs the pot. They can't touch the puck, but can hit anyone. Something along the line of bludgers from qudditich.
