Mega Evolution's revolutionary gameplay features are included in the brand new Pokémon collectible card game expansion XY! Mega Evolution Pokémon are cards created from Pokémon EX that are powerful in their own right and possess unimaginable powers that will affect Pokémon TCG players in terms of deck building and battle strategy. However, players should consider carefully whether to subject a Pokémon such as Bisaflor-EX or Turtok-EX to mega-development, as this immediately ends their turn and makes them unable to attack. However, the risk has paid off as mega-development Pokémon are stronger than Pokémon-EX. The mega-development Pokémon dominates every battle in the Pokémon trading card game with its tough attack and high KP.
