probably the most unique groudon card on earth!
What’s the functional purpose of a “discard” end sheet card? Do they usually get bad cuts due to them being on the tail end of a sheet?
When on a normal sheet of cards, the typical purpose is to fill out the sheet. Sometimes the number of cards going onto a sheet does not equal out to the number of spaces on the sheet. Theme decks or certain promo cards are good examples of this. Sometimes this space is blank, or has borders, or some text printed on them. In these cases they are considered Filler cards.
However as discussed a bit previously, it is a decent theory that this Groudon is some form of test print rather than a Filler card. In the case of it being a test print, the “discard” might have been on every card so it was clear they were all tests. Like the For Position Only or Jpn dppt TEST cards.
