What are some cards that might be overlooked or not talked about enough nowadays? My personal favorites, which rarely come up, are the 2015 Hoopa promo (XY-P 155) and Umbreon (BW 93). Both are pretty reasonably priced, considering what they are.
Hi I am working on a Pokemon sealed Tracking Tool. I am using the 7d avg cardmarket prices for tracking. There are some downsides like in the sheet. Cardmarket does not provide access to past prices. This is a limitation. Let me know if you would like to test it and use it productively. I would then adjust the final details and translate it into English. I would have to charge a fee for this in the future because it incurs ongoing costs. I may include cards in the future.
