I don’t care that these aren’t playable. Poliwhirl is my favorite Pokémon and I love this line in general! Definitely picking these all up for my collection! :D
There definitely is a market for miscut cards, as people love to collect them. I unfortunately don’t know what someone would value that at though. You want to look around some places like eBay or possibly other websites collectors may us. Or maybe even ask someone at a local game store to see...
