The goal was to earn cards by going above and beyond expectations (i.e., doing something nice for someone, meeting behavioral goals) and trading cards with peers until a full set was made
The price of any asset is controlled by supply and demand, and Konami has perfect control over supply of any card and a strong influence over demand
The case comes with 12 foam blocks to act as stoppers within, to ensure your cards arent rattling around inside during transit, and the exterior is made of a super-tough polycarbonate material that withstands pretty much anything that might happen during day-to-day use
It could be possible that the card was originally intended to be that sets centerpiece but subsequently shelved until Bandit Ring [XY7], the next set
Players could always try to negate this effect, but cards and effects cannot be activated in response to it, so the best way to counter it is to negate its summoning entirely
