First of all, how good of a tech is Dialga Gx?
Second, I'm foreseeing a rise in mill decks after rotation, and if this is the case, is Metagross a good counter? It seems to me that the built in discarded energy recovery that comes with metagross can deal with energy discards, Dawn Wings plus Altar of the Moone would solve Special conditions, and Dialga Gx 'Shreds' through Safegaurd 'Mons.
