Make sure you take in many good health potions and things like that as they could become invalueable in the times you need them most

Get your Empoleon and Luxray to 60, bring about 20 Full Restores, 10 Revives, and a few hyper potions. Those are the only 2 pokemon that you really need to beat Cynthia.

Bring about:
20 x Full Restores
15 x Revives
15 x Full Heals (because they like to give your pokemon status problems.

Level up your Luxray and Empoleon and you should be alright.
(You may want to try and match up your moves to the Elite Four's pokemon types to give yourself an advantage).
