Character info
The character
Greninja is the final evolution of the Froakie line, a Water-type Pokémon from the Kalos region first introduced in Pokémon X and Y. It is known for its ninja-like appearance, speed, and the water shuriken it forms and throws at opponents. Through Mega Evolution, Greninja gains an even more dramatic, armored and bladed form, with a scarf-like tongue and enhanced shuriken-based attacks.
This card
This is Mega Greninja ex, card number 022 out of 86 from the Chaos Rising set, printed as a Holofoil in the RR rarity. The artwork, illustrated by takuyoa, depicts the Mega-Evolved Greninja mid-motion surrounded by water effects and throwing stars. The card carries a Stage 2 designation, evolving from Frogadier, and bears the Mega Evolution ex rule marking on its lower text box.
How it plays
Mega Greninja ex is a Water-type Stage 2 Pokémon with 350 HP, weak to Lightning-type attacks (x2), no listed resistance, and a retreat cost of one Colorless energy. Its Ability, Mortal Shuriken, lets the player discard a Basic Water Energy from hand once per turn while this Pokémon is Active 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 to add 80 more damage. As a Mega Evolution ex, if this Pokémon is Knocked Out, the opponent takes 3 Prize cards instead of the usual amount.
