Ah, correction- Shaymin is on-par with most other strong Pokémon, and most other legendaries are statistically the strongest type of Pokémon in the game.
I wasn't talking crap, i was givin my opinion and everyone on this builleten post agree's with me (except for you know who). Also there is no need to be a potty mouth.
The harder the fight, the better the prize...well, hopefully.
