Character info

The character

Mewtwo is a powerful Psychic-type Pokémon created through genetic engineering from the DNA of Mew. Introduced in the original Pokémon games and the first animated film, it is known for its immense psychic power, cold demeanor, and recurring role as a formidable antagonist or ally across the franchise. It frequently appears in the Pokémon Trading Card Game as a high-HP Psychic attacker.

This card

This is Mewtwo GX from the Hidden Fates set, numbered 31/68, printed in 2019 as a holo rarity card. The artwork by aky CG Works depicts Mewtwo in a dynamic crouched pose against a dark, reflective holographic background. The card uses the GX card frame and treatment typical of this era's special illustration rares.

How it plays

This Basic Pokémon has 180 HP and is Psychic type with a weakness to Psychic (x2) and a retreat cost of 2. Its first attack, Super Psy Bolt, costs two Psychic energy and one colorless energy and deals 110 damage. Its second attack, Psycrush GX, costs the same and deals 120 damage while discarding all Energy from the opponent's Active Pokémon, with the standard GX rule limiting its use to once per game. As a GX Pokémon, if it is Knocked Out the opponent takes 2 Prize cards.
