Over two turns, you get three +1/+1 counters on everything you control, or more if you can pump the Ouroboroid before combat
That's what sites like TCGPlayer are great for, finding single chase cards, at the best price possible, and not having to spend thousands on sealed packs with overinflated prices
To each their own, but if you could purchase a card raw for a little over $100 why would anyone in their right mind want to pay over $50k
Borderless Vault Boy Eight of the nine Borderless Vault Boy treatments are reprints, with the only new card receiving the treatment being Nuka-Cola Vending Machine
Although Charizard has never been officially classified as a Dragon type (despite Alolan Exeggutor somehow making the grade) he still makes it into the Sun & Moon Dragon Majesty special set (special in the sense it couldn't be bought in booster boxes and was only available in collection boxes, pin boxes etc.)
