I Won A Couple Blitz Ball Games With Em, All You Really Need To Do Is Replace "Jassu" And "Keepa" With "Wedge" And "Biggs" And Replace "Wakka" With "Brother" And Pretty Much Keep Everyone Else. Now Thats A Team! But Yeah The Aurochs Are A Bunch Of "NOOBS" You Just Gotta Throw Out The Crappy Members.
If Anyone Wants To Know Where To Those Alternate Blitzball Members Feel Free To Ask.
I've kept hold of Jassu, my main defense is Botta and Judda, but in the easier games against Kilika or the Ronso, Jassu will play. He's not too bad.
Biggs is at the front on mine. He's got a good attack, but his PA is weak, so don't use him as a defender, plus he has a good shot. Never heard of anyone putting Wedge in goal though, plus Keepa is a pretty good GK if you work with him.
Plus, you don't need to replace Wakka, he leaves any way, you can resign him later on in the game. So unless you mean replace Datto with Brother...
