Strange. Usually during most pokemon challenges it's taboo to use any starter because most of them are OP. I personally wouldn't participate in this because it seems like it'll be extremely easy, but I think this challenge has inspired me to create a 6-starter competitive team. Good luck to anybody participating in the challenge!

I think that you should add the rule of having at least one starter from each generation (don't know whether this is already a rule).

IN FACT COUNT ME IN! This challenge feels like it'd be fun. Btw you might want to advise people on using Pokemon bank to safely secure their teams/pokemon already on their x/y games.
