Just a few days ago, I had this team:

LF: Eigaar
RF: Tidus
MF: Brother
LD: Balgerda
RD: Ropp
GL: Nimrook

But then I learned about the Aurochs' connection to Wakka's final limit, so now it's:

LF: Tidus
RF: Brother
MF: Wakka (until he is levelled enough to actually score any goals, when he'll become a Forward and Letty will take this place maybe)
LD: Botta
RD: Jassu
GL: Keepa

It's not like it's any trouble winning, anyway. By the way, does Wakka count to improve Aurochs Reels? And those warming the bench?
