I recently received a few EX and Mega - EX Pokemon cards that I am suspicious are fake. The holographic part covers the entire card, and isn't detailed, it just makes the whole thing shine. The colors seem a bit off. Not only the front but the back is waxy. It doesn't feel like other EX cards I have. The cards seem off-center. There is not a line running through the center of the card if you look at the edge. Are these fake? (The cards are Gardevoir-EX, M Diancie-EX, M Manectric-EX, and Lunala-GX.)
This seems pretty fake to me. How 'bout you get some tape and rip it apart. If it doesn't have some Black Markings inside, it's fake. But it's real if it does.
