I do have a few things to EV train if really interested in my tornadus:
#1: sassy munna, ability=telepathy, 252 hp, 252 sp.def, 6 sp.atk
#2: sassy munna, ability=synchronize, 252 hp, 252 sp.def, 6 sp.atk
can take away baton pass on both above in favor of an attack such as psychic or shadow ball if needed.
