The second scenario is much different, but the outcome remains the same
If I have a card that I spent $1500 on a year or two ago, and I invested that money, because the company said they wouldn't print any more ever, and then the price rises to $3100 for its condition, and then they announce the removal of the Reserve List tomorrow, and by the end of the week we see that it's going to be a mythic rare in Eternal Masters 2, I think that would be the worst feel bad moment ever
While some of their cards are restricted in the TCG, they have no such restrictions on Master Duel
