pokemon battle revolution has ten colosseums to battle
At the reception desk, the receptionest ms.anna will give you a tour of the colosseum mode menu. You can go right into the Battle function, but it might notbe a bad idea to check out the storage function to copy your pokemon from pokemon diamond or/and pokemon pearl, or register your birthday and intro in the profile function. Give all of the functions a try to get the hang of the game and check out the tutorial mode to find out how to battle and then go to your first colosseum gatway coloseum.
