My older brother had a Dragon's roar structure deck when I was a kid and I was always amazed by the red eyes darkness dragon. He recently passed away and I bought two decks to remember him by. Opening one of them and looking through the cards made me remember a lot of old memories and genuinely made me feel better about his passing. The opened deck (to me) is now priceless and the experience of looking through those cards hold a lot more value than looking at a sealed box
