The eleventh set of the XY expansion is going to be XY Steam Siege. This set will feature a lot of new Pokémon EX, including of some that we haven't seen as cards until now. Pokémon like Vulcanion we be released alongside some new Mega Evolutions, including Mega Salamence, Mega Mega Steelix, Mega Sableye, Mega Banette, and Mega Beedrill, which will bring us a step closer to featuring every Mega Evolution in the Trading Card Game. We will have to see which of these cards will impact the game most, but I can asure you that the set will feature one long awaited card that will definitely see a lot of fans. I'm talking about Prof. Sycamore who finally will get a Fullart version, after being reprinted in so many sets, without getting one. Overall this set will feature more than 100 new cards to add to you collection.
