Card deck search does not work

Same here - only Pokemon cards in hand are treated as such, it a card is in the deck then search cards do not treat them as valid. What a horrible error, which affects my on Windows but not on Android phone.

Some cards versions may not work on PC. Try to avoid playing older or weird versions of cards. I had this problem 100% of the time. Swapped my old boss order for a recent one, and I don't encounter it anymore.
