The more I sit and think about it, I think Japan intentionally is trying to kill Blastoise and Emboar off. Why? For the sake of the Japanese players at worlds. Being that Beach is banned in Japan, hypothetically, someone coming here would be forced to pony up $400-600 for a playset for 1 tournament. They can't exactly suddenly tell the rest of the World that Beach is illegal, so what's the simplest manner of dealing with the issue? Kill the major decks running Beach. Blastoise and Emboar both can be crippled by Druddigon, in some matchups so much that it swings the game easily. Of course, decks like Trevenant and Flygon still exist and use Beach, but the only reason I can see them printing a clear, hard counter to these decks is to neutralize Beach's impact on Worlds. With rotation possibly claiming BCR (and with it, Shell Shield and Skyla), both Emboar (Rayquaza goes) and Blastoise will be dead anyway, resulting in Druddigon's utility likely declining. It seems they figured they could get away with the hard counter for 3 months, and so far, I'd say they've succeeded. I just can't see Blastoise beating a well-prepared list/player.
