Released on May 6, 2015, Roaring Skies is the sixth main expansion of the XY series, dominated by the Legendary Pokémon Mega Rayquaza-EX in both its Dragon and Colorless forms. The set features powerful Pokémon-EX including Shaymin-EX — whose Set Up Ability made it one of the most essential competitive cards in the game's history — alongside Gallade-EX, Hydreigon-EX, and Thundurus-EX. With its game-defining Shaymin-EX and the sheer power of Mega Rayquaza, Roaring Skies remains one of the most competitively influential XY-era sets.
