Copper is a Clue that can be located by adding the Ultra-Rare of Card Pack 1, Card 60: X-Ray.


Card 60: X-Ray


Amy and Dan's mother, Hope Cahill, never took an X-Ray exam. Nobody knew why, but the shocking truth was revealed when she was hurt in a car accident: a special computer chip in her wrist contained data about a Clue.


The scene first shows an X-ray of Hope's arm. It zooms in on the microchip. The X-ray decodes it, and after that, the X-ray disappears with stripes of blue light, and the word COPPER appears.
