It would have to be PO, I have no time for wifi anymore (not to mention I lack a good wifi team)
You see, I used to battle singles a lot before real life strengthened its strangling grip upon me.
I had just come up with a couple of good teams, after a bit of testing.
However, before this, I had made around 80 team files but was too lazy to organize them.
I forgot what teams were the good teams, and which were the not-so-good, thus losing them in a sea of filenames.
