Magnezone

How does one evolve Magneton into Magnezone? Is there some secret event that you have to trigger to be able to evolve it or what? Do I need a specific location or something? I have both ep11 and ep 13 so if its easier to get it in one ep then the other then please do tell.

You'll need the Yureyu Key to get into a certain portion of Shade's Gym in the back where you can evolve it by leveling up Magneton inside.

It doesn't matter which episode you are in. The key is found by entering the cave Saphira came out of, which is in the western corridor of Tanzan Mountain, and following that path.
