I would run psyshock to take on special Walls (blissey Lols in your face and jelly resists your other moves). You can still hit most steels neutrally with scald anyway.
Smogon is appearantly in the process of writing their analysis on him, but I don't quite follow the EV spread the author has (252 HP / 180 Def / 76 Sp. Def). It seems to me more Special Defense would be useful. His stats with that spread come out to 394 HP / 241 Def / 302 Sp. Def. Is this a good EV spread or is there a better one?
