Dialga (XY77) is a full-art promo card from the 2015 Pokémon XY Black Star Promos series. It features Dialga, the Sinnoh-region time-controlling Legendary, illustrated in dynamic detail by TOKIYA, with a foil background that highlights its steel (Metal) type. This Basic Pokémon card has 120 HP and attacks like Metal Claw and Time Freeze (which stops opponent Pokémon from evolving next turn), making it playable in the TCG. The holographic full-art design and rarity of this promo make it a standout collectible for fans and players alike, adding nostalgic value from the XY era to any collection.
