You know, probably around this time last year, I was planning a BD challenge with help from Luke (idk his current username whoops). It was coming along great and I probably still have the stuff saved on my computer, but I never did get around to posting it. The idea was using a team of 4 and you could have any combination of jobs you wanted and there was a list of the jobs and how they function in the Pokemon world. But generally, no, I don't think it'd be overly tough. I think it'd be a fair challenge. :)
