Alrighty. I didn't think there were any permanent rewards from the Exhibitions, that they were just practice. It's cool to know there is some reason for them.

That being the case, you can always save-reset when a new tournament is about to start to randomize the rewards, if you want. I got one of his Key Techniques through a Tournament reward, I think.

That being the case, JS2 is still useless. Costs over 10 times as much HP (so it can't be spammed nearly as well), and, since it uses Invisible Shot mechanics, it can miss no matter how big a Shot score boost it gives Tidus.
