Where this card came from
Mewtwo EX is a Japanese promo card, as part of Battle Festa. It carries the card number XY-P, from the XY-P-series Japanese promo line.
Promo cards are not sold in booster boxes. They reach collectors through a specific campaign — a store, a museum, a film, an anniversary or a championship — which is why the printed number is the only reliable identifier: the same Pokémon can appear on dozens of promo cards across the same era, and the number is what separates them.
That is also why this card appears in our celebration, collaboration and event index rather than in a set list: nothing here came out of a booster box.
