I believe, as do many other Pokmon TCG collectors and content creators alike, that the Center is giving these codes out in waves
Way too expensive and inflexible to see play
I seriously wonder if they were worth the trouble to this day
I can definitely understand people not putting Yawgmoth, Thran Physician in their top five list as its only played in one deck, which isnt a dominant player in the metagame either, but the card makes the archetype and there arent too many good mono-black creatures in Modern right now
Understanding Chase Cards These are the cards everyone wants usually high-rarity, low-print, and packed with character appeal
Water decks have, in my experience, been the most prominent type of all decks in Pokmon TCG Pocket so far
