Probably until you meet your Rival on it

Ok...its really hard to beat the pokemons of Pokemon tower...When i beat 10 trainers of the battle tower(single),i got an item called Upgrade...
It doesn't matter about the wins. Just get an awesome streak. The leader of the battle tower only battled me when I used crappy Pokemon like Manectric, Dustox, and Dusclops. Although dusclops was pretty good. I still beat him anyway.
you can go back to Twinleaf and go to your rival's house, i dont know maybe what i did was what happens when i use too many cheats. i used lots of cheats to do get a 100 win streak in the battle tower
theres many things to do, provided you want to do them. 1) beat battle tower and get 100 kills in a row 2) find all the legendaries 3)complete your pokedex 4) try and get as many level 100's as possible
ok this seams crazy but u must beat the battle tower a bunch of times.(im not sure how many, but i know it from somewhere.)
2 1) Zombie Boy 2) Lady Gaga
Battle tower medals? 2, but there are the other pikes to think of, too. That'd total up to 14 medals.

Easy just get as many plant or water type pokemon and you will beat it
