Colluseum (sp?) Help

For some reason, I just can't be Evice!!! I maybe can take down 1 or two of his Pokes, but never anything more. My team consists of:

Level 54 Noctowl
Level 62 Typholosion
Level 62 Metagross
Level 55 Quagsire
Level 55 Espeon
Level 55 Hariyama

What should I do just to beat him!

I think your Pokémon need more training.

That is what they needed, I got them all to level 58+, I just took him down in a matter of 5 minutes xD
