Pokémon FireRed and LeafGreen/Pokémon League Rematch

Well, you've done everything you could on the Sevii Islands, so you decide to take one the Elite Four again. Well, If you haven't already, make sure your Pokemon are level 65+ unless you're feeling very confident. Why? Well, unless you want your butt kicked, I sugest you do it. All of the Elite Four members have leveled all of their Pokemon by 10, so you should too.
