Character info
The character
Greninja is the final evolution of the Froakie line, a Water-type Pokémon first introduced in the Kalos region games. Known for its ninja-like speed and shuriken attacks, it later gained prominence as Ash-Greninja in the Pokémon anime through its unique bond with its Trainer. It is widely recognized as one of the more popular starter-evolution Pokémon due to its design and competitive presence.

How it plays

Its first attack, Stealthy Slash, costs one Water energy and deals 30 damage to one of the opponent's Pokémon for each damage counter already on that Pokémon, without applying Weakness or Resistance for Benched Pokémon. Its second attack, Aqua Edge, costs two Water energy and deals 160 damage. As an ex Pokémon, when it is Knocked Out, the opponent takes two Prize cards instead of one.
