So a gold Black Cat card randomly appeared in my monster select screen. I didn't catch any black cats, as you start out with two. The gold card has the same stats and everything as a normal Black Cat, but the outline is gold. The only real difference is that the stuff i need to evolve it are different, and its a lot more expensive. I googled around for something about the card, but i came up with nothing. Can someone explain to me how i got it?
