Basically, I need to beat Don Tonberry. I have Ultimate weapons for Yuna and Auron, and both have completed their grids BUT I'm a wimp compared to the powah of Don Tonberry. But I can make a Trio of 9999. What should I do? Should I use Trio of 9999 liek, 30 times cause my characters will be dying in, liek, 1 shot? >______>;;;

Just answer me dammit.
