Secret Rare Cards

How do you know if some cards are Secret Rares? Well, look no further, I will tell you. First off, look at the card on the side. I have this card and I know its a Secret Rare because of its texture. Its, golden shiny and also scratchy. Also, if you look very closely on the bottom right, there will be a number. It says 100/98. How is that possible?!?! Well, it's how the card is made. That is how you indetify a Secret Rare.

An example is Flying Pikachu
