hey, did anybody know that there is a glitch in colloseum where if you on your first turn, then when you are selecting what two do for your second turn, go back into the ball bag and on the pokeball you selected the previos turn, you select using X and switch it with another pokeball, then doing whatever you need to do with your attack, and when you check again, you will have all of the pokeballs! here is an example:
Umbreon lv 27-----------
Makuhita lv 30
---------------------vs----------------------
Espeon lv 26-------------Spinarak lv 30
pokeball bag: Pokeball x5
Great Ball x5
Umbreon's turn: select Great Ball from bag to throw at Makuhita
Espeon's turn: go to bag and switch Great Ball with Pokeball and attack Spinarak with Confusion
Makuhita's turn: weakened previously and captured by Great Ball
Spinarak's turn: fainted by Espeon's Confusion
pokeball bag: Great Ball x5
Pokeball x5
this trick also works great with the master ball
