For blitzball i would find the best charecters reset the system then get them on ur team. U can get wakka,wedge,and when the al bhed drop him their goaly!

You train lulu! HA! I just took and used a tele sphere to get yuna on lulu's track so now she has white magic and black magic and ultima! Auron took wakka's grid for accuracy and wakka took arun's for power
