you should get all the celestial weapon, that if you want a perfect game (like me). If you really don't want to, get Yuna, Auron and Rikku celestial cause that the only easy one.

The Kupo Man, you're lying cause if you want to get Status Reels, you have to win the league, league-10 games so I can say that you're lying.

I think Tidus sigil is a lot easier than Kimahri and Lulu, cause if you press R1, R2, L1, L2 at the same time, you can balance the chocobo well. So you just need to press R1, R2, L1, L2 till the ned of the game while avoiding the bird and getting the balloons.
