I have, like 20 times. It's easier if your blitzball team is full of original Besaid Aurochs, Tidus, Datto, Letty etc... that way, more Auroch icons appear.

It's one insanely powerful attack, which is great, unless you've maxxed your stats and do 99999 damage a hit, which then your perfect Auroch Reels does as much damage as a normal attack, and Attack Reels becomes the more dominant.
