Misty’s Pysduck

Cough. Yes, obviously this card’s going to do well. Everyone loves Misty, some rather too much, and here she is in her swimming cozzie. It does help that it’s also a completely lovely piece of art, with Psyduck looking so cute.
The Japanese version, from Heat Wave Arena, seems to sell for around $26, which is incredibly low. I imagine it’ll be double that in English by this time next month.
Its ability allows you to discard the bottom card of your deck, and then when done, discard any cards attached to the Psyduck and put the card back on the top of your own deck.
