No GG isn't really even played over there. And magmortar isn't really played with typhlosion but just magdol with pachi.

Dang, I like that Kingdra!!!
actually, ive recently read articles on ohter sites and found that GG is actually one of the most played decks in Japan. The japanese use it with techs like Gardy DS and mewtwo Lv.X and Azelf lv.X to shut off weakness. also kingdra DP5 is an extremely popular card there as well.
