Pokmon Tournament Rules Handbook states that Cards that have undergone post-production alteration, [including] autographs, artwork, or other such amendments to the surface of the card, not including any official stamps applied by TPCi [are disallowed]. Like altered cards, damaged cards are also not legal for tournament play if their damage is substantial enough to potentially be visible during play

These cards tend to break normal design rules and formatting, so itd be cheating to place this in the black bordered list

Same with Embraal Bruiser

Throwing in your cards willy-nilly doesnt hurt anything, but both players engaged in a trade will find things easier if you have some sorting method
