Make sure you write what game do you play... if you have Fire, Water/Ground, Electric, Flying, Psychic/Fighting, and Grass type, I'm sure you will be able to beat elite 4! hope this usefull...
Pretty much any team thats even moderately balanced can beat the elite four. Personaly though, I have grass,fire,water,dark,psychic,and electric.
