I just now beat beat Jasmine.
My current team is:
Feraligatr Lv. 37
Gengar Lv. 30
Quilava Lv. 27
Togetic Lv. 21
Pidgeotto Lv. 26
Bellsprout Lv. 16
Totodile was my starter by the way. In case your wondering what's up with Quilava and Gengar, my brother came over with his copy and decide he wanted Chikorita so he traded me his Cyndaquil And then he started over. And then while we were at it I had him evolve my haunter.
This game is so awesome.
