Okay I did it the easy way since Volley Shot came up in the 3rd place prize for a tournament, I simply lost on purpose in the second tier, it was surprisingly difficult since I scored by accident from my goals lol. But eventually the right combination of strikers in goal and keepers up front and I got beat. I then just faced off for third place and got Volley shot that way.

But it's decided though, I couldn't get Venom Tackle 3 because of not having Volley Shot. I wish Blitzball had made that a little more clear or at least not highlighted it leading me to believe I could get it
