A Simple Team to beat the Elite Four
All you really nedd is a Kyogre lv.55 and it should know Ice Beam, Blizzard, Hydro Pump, and Body Slam.
You should also have plenty of revives and hyper potions. It would help to use a PP Max (Get from trick house challenge 5, 6 or 7) on Hydro Pump. Use Hydro Pump on almost every foe (It is EXTREMELY powerful [emphasis on "extremely"]) except for Glacia's Pokemon, you would want to use Body Slam and also the grass pokemon, you would want to use Ice Beam or Blizzard.
