omg....Lets be Honest Xerneas is only S tier Because Of Geomancy and Power Herb Although i do enjoy the combo Myself.....If It were fair Xerneas would be B tier But its Not That's why its in Ubers But S Rank is a little High I would Move it too A or A- because it can be shutdown By Any prankster pokemon with Thunder wave
Edit: Xerneas usually runs Aromatherapy to cure it from status, and there aren't really any relevant Taunt users besides Deo S and Yveltal, which both Xern can handle
