This card was included in the Hidden Fates expansion, first released as part of the Japanese Sun & Moon Family Pokémon Card Game set. Full Art and Rainbow Rare versions were subsequently released as in Japan as SM-P Promotional cards in conjunction with the release of the Remix Bout subset. Participating Pokémon Centers, Pokémon Card Stations, and stores hosting Pokémon Card Gym meetings between July 5 and September 1, 2019 held Mewtwo HR Competitions, which were Limited format tournaments. People wising to reserve their position could do so for most venues through the Player's Club website.
Entrants received 15 Remix Bout packs and 15 copies each of basic Grass, Fire, Water, Fighting, Psychic, and Darkness Energy cards upon paying the entry fee and were required to construct a 40-card deck to use in matches with 4 Prize cards. Each tournament consisted of multiple 4-player round-robin qualifying rounds with the top player from each group going on to compete in the knockout stages. Those reaching the knockout stages were given a copy of the Full Art version of this card while the overall winners of a tournament were given a copy of the Rainbow Rare version. An invitation-only Mewtwo HR Competition, which served as a Remix Bout prerelease event, was also held at the NicoNico Honsha, Ikebukuro, Tokyo on July 4, 2019 to decide the first winner of the card. In total, only 300 copies of the Rainbow Rare version were awarded. All prints of this card feature artwork by aky CG Works.
