PUR is the best rarity in the game, period. QCR has way too much shine and you can't see the card art for shit, platinums are literally a downgrade from QCRs, Ghosts are so immensely overrated and if you breathe on the card it gets damaged. Collectors are cool but kinda meh, and Prismatic Collectors are UGLY AS SIN with those shit ass glitter sposts.
The only rarity which competes with PUR is the original Ultimate, and still the PURs are way cooler.
