Theres quite a lot of text on each card as the designers work to capture their unique character, but it helps if you start by reading the Vehicle side first
It's unclear whether someone has managed to snatch these cards before they've been released, or if this is a scam of some kind
For example, Heritage Auctions hosted a bidding war for a Charizard #4 first edition base set rare hologram card, which reached over $100,000 in January 2021
If you are wondering why left/right but not top/bottom has a chance to be forgiven for flaws, its because PSA slabs will "hug" the left/right of a pokemon card size perfectly but there will be some room top/bottom for the card and corners are wide open to view
Not everything comes in a Jumbo but they have some really good artwork like you mentioned
