Background
Mewtwo & Mew GX 52/173 is the 2019 Japanese Double Rare from SM12a Tag Team GX: Tag All Stars, released 3 October 2019. Art is 5ban Graphics. CARDZ files the Japanese RR identity on collector 52/173.
Ability Perfection lets the pair use an attack of any GX or EX in play on the Bench or in the discard. Tag All Stars was a high-class pack that reprinted popular faces from the Tag Team block.
The card is a two-Pokémon TAG TEAM Psychic line, not a later Fusion Strike or 151 Mew face. Keep set code and 52/173 before lining it up with English reprints.
