About this card
Three months after Ultra Prism, Forbidden Light printed a second Dialga-GX, and on paper the two are the same card: 180 HP, the same three attacks with the same costs and the same wording. Only the element moved, from a Dragon weak to Fairy over to Metal, weak to Fire and shrugging off 20 points of Psychic. The painting is new as well, the head turned down to the left and the fin blades sweeping across the right of the frame.
