Ok. Lucario is pretty tough, being a Gem Guarddin.I beat him today without using a Pokeassist.(not bragging But hwne he uses is aura sphere stop and when he takes a breka start and then stop. When he sends out the bolt things just be careful. When he has his aura around him, watch out for the things I said. It should be easy! Oh and, bring a Raichu or 2!
