if i have learned anything through two BRs it's that GG is still boss and looks to be for months to come. yes empoleon is good, but A) a lot of it's success is coming at the expense of magmortar and B) there is nothing inherent about empoleon which gives it an advantage over GG (don't tell me it's holon wp energy either). i would rate it as the new second best deck going. so unless a very good ghost deck comes along (i mean, it has to be better than banette) that can give GG fits AND survive all the rogue matchups i think GG might be the dominant deck so long as it is format legal. has this ever happened before, where a pokemon line was introduced and it dominated for its' whole legal existence? i have looked casually at the next japanese set and while things like kingdra look great, i can't say i saw anything which was going to become the new king of the hill.
