A good Lightning pokemon or grass pokemon can get the job done.
yes as the person above said a good grass and lightning pokemon will get the job done also make sure your grass or/and lightning pokemon is level 55-60 as his milotic is level 58. if u have a lighting pokemon make it sure it knows an electric move at least power 70+ same for grass pokemon electric pokemon move: discharge, thunderbolt or thunderpunch grass pokemon move: energy ball, solarbeam or leaf tornado hope this helps!
