Just saying keep going in until you get stronger and stronger that is how I beated him.
I had this problem too. I got passed it by going back to my storage (before you go into the tower) and brought 5 Reviver Seeds. My Pokemon were lvl 42. If you don't have any Reviver Seeds than train after you go half way through the tower. I actually only used 2 of the seeds.
