No no no WPM, he means the borders on the face of the cards not on the backs. Originally I knew we had gold borders because of the e-Reader code strip at the bottom of cards. Now those are gone, so the only reason I believe we have gold borders is to easily identify Japanese cards (besides looking at the text) from our own. This is especially handy for judges in tournaments, if we know the border color is different, then the back of the card is going to be different. This is relevant when it comes to using cards with multiple backs to ensure the player is using sleeves as well. That is my opinion.
