@Dyl i just bought 3 packs of old maid, waiting for shipment. I really loved old maid as a kid so this is was a must have for me. Going to open one for the binder and keep the others sealed. The artwork is great, and nice contrast to the typical cards.
Do you know anything about the print run? It seems like they only ran it for one year in 2019 from what I can tell.
They are pretty neat cards, but they are definitely not hard to come by. Pokemon Center Japan restocks them every now and then. Right Now they are in stock and limited to 2 per person. https://www.pokemoncenter-online.com/?p_cd=4521329266527
This Eevee card was $200 pre-boom, went above $300 during boom, and has been slowly coming down since. It is now under $100. Might be a good time to pick it up if someone here needs it.
