Dialga (sm8-127 Reverse Holofoil) is a Metal-type Basic Pokémon from the Lost Thunder set. Its Turn Back Time attack devolves an opponent's Active evolved Pokémon by returning the highest Stage Evolution card to the opponent's hand, and its Power Blast deals heavy damage at the cost of discarding an Energy. It has Fire weakness, Psychic resistance, and a two-colorless retreat cost, which informs its defensive and energy-planning role in decks.
