Mega Camerupt ex, Mega Absol ex, Mega Mawile ex, Mega Abomasnow ex Revealed!
Artwork for Japan's next set of Gym tournaments, called the "MEGA Summer League," all but confirms Mega Absol ex and Mega Camerupt ex will be included in Mega Brave and Mega Symphonia. The tournaments will start on August 1st, the day the sets release. Each deck must include two or more Mega Evolution cards.
Update: A marketing photo for the tournaments has revealed Mega Camerupt ex, Mega Abomasnow ex, Mega Absol ex, and Mega Mawile ex! They are too small to translate.
Mega Gardevoir ex, Mega Lucario ex, and Mega Latias ex have already been revealed, and we knew Mega Kangaskhan ex would be included in the sets thanks to the Ultra PRO portfolio for our Mega Evolution set. Mega Venusaur ex isn't shown on the artwork, so it doesn't represent all the Mega Evolutions that will be included in the sets.
