Sure, there would be a limit to it. Such as time that is needed to sort through the memories, implant the memories etc etc. Nothing instantanious. But how fair is it to be up against a Pyromancer that can melt your face with a thought? Or an Electromancer that can manipulate magnetism which is control of everything metal. Hell, using Magnetism to become a human rail gun for Gods sake. Nothing is fair when you take time to think about it.
