Hey,
First off im new so if this has been posted then feel free to remove it.
I love watching Scrapyard Wars, its one of my favorite parts of the channel and I always look forward to every episode. Therefore I had an idea of where it can be Linus, Luke and maybe another special guest going against each other, however they also each have a fan of the show with them. So it can proceed as normal but the fan of the show must make the decisions, whilst Linus etc must be there to help them build it and let them know if the parts they are choosing are compatible or not.
Please feel free to leave your thoughts on this idea and like i mentioned previously, i apologise if this has already been posted.
