Wow these are some VERY cool cards, especially ike azumarill and the break cards (i want some of them!) ! im jealous! it would be a bummer if they were fake but one way to check if they are real is by checking hte colour on the back, it should be a kind of dark yet kinda light blue, and also the texture of the cards. if it feels like paper, probably fake. if your hand cant properly run across without friction, its probably fake too. Hope this helps!
