However, with the destruction of the Magic Empire, the disadvantage of the arcane cards had instead become a feature avidly discussed by adventurers.
Since the cost of arcane cards was relatively high, the items stored within them were more valuable, and their one-time use also ensured that the arcane cards would not be prematurely explored by others.
Of course, this wasn't a certainty,
just like how some mages would store personal items in arcane cards, such as magical photos of loved ones, letters to a lover, and so on.
Also, since the Magic Empire existed a long time ago, many of the magic items and knowledge that were precious at that time might not have much value now.
This made opening arcane cards somewhat a gamble, and later some high-end casinos even offered gambling on arcane cards.
However, as time passed, the vast majority of arcane cards were opened, and gradually arcane cards also became cherished.
