Some useful information I found while playing Pokemon Colosseum even though I hate it. When you get the Master Ball you can use it more than once so you can easily catch the last few Pokemon on Pokemon Colosseum.
1st Pokemon Move: Use Master Ball on Shadow Pokemon.
2nd Pokemon Move: Swicth the Master Ball around with another Pokeball.
Doing this will use the Master Ball and you'll still have another one for later. Also when you do this no Pokeballs will be used so it's a very useful glitch. Hope that helps some of you people who wonder what to use the Master Ball on. Metagross, Tyranitar, or both?![]()
