Here is a glitch to get unlimited masterballs in the game pokemon colosseum! After you get all of the badges in the realgam tower(After defeating Mirror B., Dakim, Venus and Ein) you will get an email from Eagun(in Agate), but the message is cut off so go visit Eagun before moving on through the realgam tower. Eagun will give you a masterball. Here's the glitch! Whenever you go into a battle and a shadow pokemon appears you must have at least two pokemon in your party a pokeball, great ball,ETC..., and the masterball! Select the masterball with your first pokemon and with you 2nd pokemon go back to where you selected the masterball in the bag and hiy the"Y" button on the controller and switch the masterballs place with any other ball in your bag! You will be able to attack with your 2nd pokemon, but your first pokemon will use the masterball. After you use it check back in your bag and the masterball will still be there! Sorry it was so long!! Hope it helps!!!!!!!!!!
