pokemon cards rarity chart Acquisition for all : r/PTCGP The English Pokémon card rarity

Released in the fall of 1998 in Japan and in the summer of 2000 in North America

It sold in 2021 for very close to a staggering $250,000 and, as far as the world of buying and selling works, it remains the only one in existence and is technically the rarest Pokmon card of them all

Going further, running creatures such as Restoration Angel, Felidar Guardian, and Corridor Monitor will give you ample ways to end the game

Therefore, if you are considering combo, my recommendation is to either have a combo that slays everyone quickly or add a few combo cards to decks that already exist, and if possible, to have those combo cards not look shockingly out of place
