The name of Japan’s XY6 is Emerald Break and will hit store shelves on March 14th. There will be 78 cards in the set, excluding secret rares. As its name implies, the set will feature Rayquaza, most likely as Rayquaza-EX and M Rayquaza-EX. Thanks goes to Twitter user light319318 and Viper.Fox for the heads up! We should have more info about this set within the next month or so.
