thanks for commenting that was long

your team is really pretty strong. but you are missing 2 key factors.

1: your monferno. he is WAY to o weak to be fighting the E4

2: you have no ice or dragon moves! the Garchomp at the end with DESTROY you!!! even your award winning Empoleon will still get killed! get a good Ice or dragon move on a fast guy!
