No, don't bother that. It's too slow. All you need to do is replace Latios... A non-Uber legendary is fairly rare though... In the Stickied PC Wi-Fi tourney in Battle Stadium, there is a list of Ubers. Just don't use what is on the list of Ubers. (Its the one with These pokemon cannot be used!) Aso, don't use a FEAR unless you use it right - Free Battle when all opponents and your pokemon are Lv 100, and FEAR is Lv 1. Its easier to use.
