That's right, I FINALLY beat the Elite Four. I warn ANYONE who has a lot of Steel in their party: Get. Some. FIRE. Lucian has a Bronzong, which is Steel/Psychic, and it has the Levitate ability, which makes it immune to Ground. So you can't use Fighting or Ground against it which are the 2 biggest weaknesses of Steel. So you can either go the route of Fire or Ghost, but good luck getting a Ghost that isn't part Poison. Anywho, here's my winning party:

Empoleon (Lv 63)
Murkrow (Lv28)
Lucario (Lv44)
Luxray (Lv51)
Dialga (Lv55)
Azelf (Lv50)

Oh, and Cynthia is the Pokemon League Chamipion. She has a mix of pokemon, including a Garchomp which is her power house. Dragon/Ground, and he pretty much 1 shotted ALL of my remaining pokemon the first time I went against him. Second time she brought him out, I 1 shotted him with Dialga using Roar of Time :3

Yeah...I'm a Pokemon Nerd. >.>
