When Prism Star cards are discarded - for instance, when knocked out - they are sent to the Lost Zone, effectively removing them from the game
Since the Charizard was in the same package, he hoped that the very valuable shiny was there too
As such this is almost exclusively used in more aggressive decks where you want a body and often (being blue) have a deficit of two drops
However, if the slab holder can hide it on the left/right of the card then it has a chance to be forgiven
