For days, you've been trying to get one of the rarest tradable cards of the game Pokémon TCG Pocket from the Deluxe EX pack: a full-art Professor's Research, featuring Professor Oak from the very first Pokémon game. You have been infatuated with this card for months, considering it can go in any deck. You've been pulling on the Deluxe EX pack for days to no avail, just getting a ton of duplicate EXs you already have, and that boring immersive you already have 6 of. But no... It's the professor you truly want. And now the limited pack is no longer available. A part of you has been considering getting it cheap on eBay, but your pride prevents you from getting it through unofficial means. Instead, you've been trying your best, messaging people and asking Oak-holders if they'd trade him for your full-art Looker. Hours turn into days, days turn into weeks and you are about to give up, until... Your phone buzzes. You unlock your phone's screen, and a DM pops up.

"Hey, you still trading that FA Looker? Wanna trade for my Oak?"
