Why a Japanese Ruler of the Black Flame box moves differently to a Japanese Ruler of the Black Flame card
A card is worth what the card is worth. A box is worth whatever people think is still inside it, so a box price falls while Japanese Ruler of the Black Flame is in print and starts climbing once it is not. That is why a two year old box can cost more than it did on release week, and why buying sealed at release is usually the worst moment.
