Character info
The character
Greninja is the final evolution of the Froakie line, a Water-type Pokémon first introduced in Pokémon X and Y and strongly associated with the trainer Ash Ketchum, whose bond with his Greninja allowed it to take on a unique Ash-Greninja form. Known for its ninja-like speed and stealth, Greninja is capable of Mega Evolution in certain games and media, gaining enhanced power and a more elaborate, blade-like appearance. It is widely recognized as one of the signature Pokémon of the Kalos region.

How it plays
Mega Greninja ex is a Stage 2 Water-type Pokémon with 350 HP, weak to Lightning-type attacks (x2) and having a retreat cost of one Colorless Energy. Its Ability, Mortal Shuriken, lets the player discard a Basic Water Energy card from hand once per turn to place 6 damage counters on one of the opponent's Pokémon. Its attack, Ninja Spinner, costs two Water Energy and deals 120+ damage, with the option to return an attached Water Energy to hand in exchange for 80 additional damage. As a Mega Evolution ex, if this Pokémon is Knocked Out, the opponent takes 3 Prize cards instead of the usual amount.
