I've read somewhere that Rayquaza and the other legendaries are banned somewhere (competitive gaming? battle arena? trainer hill?) Where are they "banned", and is Latios included in this?
Take note that I have no plans of going into internet battles or whatnot, and I am playing Emerald. I am trying to build up a good team and since I just captured a Latios, and I am wondering if I should include it in my team and replace one of my favorites, or just carry on with my 6 favorites?
