Has anyone noticed that if you chalenge the Elite 4 after you have already beaten them thier Pokemon are really strong? I know most of you already knew that, but could you give me some advice on beating the Elite 4 the second time?

Well thats kinda a weird question the only way you can beat stronger poke'mon with the same poke'mon you had before is level up your poke'mon (well duh you say) Its true if you could beat them before you can beat them again if you level up.
