I also won 2-0.

In the first half, I made sure Tidus got enough exp, then by the second half, he had learnt Jecht shot, and I used it and scored. Then Wakka came on, and I used either wither or venom shot (Whichever one he starts with) and scored the other.

So yeah, Tidus and Wakka scoring = pretty cool result.

Mind you, on my first play through I lost 4-0...
