Yu-Gi-Oh! Game Boy Bonus Set of 3 cards: Black Magician, Blue-Eyes White Dragon, and Mirror Force (Trap Card) Yu-Gi-Oh! Duel Monsters KONAMI While tidying up, I found these in the Game Boy software box, just as they were when sold. I've put each card in a sleeve since I found them. Please understand that these are from a casual collector's perspective, so I hope you can understand about any scratches or stains.
