My first two cards were a Meowth and a Geodude. I still have the Meowth but I traded the Geodude at some point :( I think my favorites are the Meowth, my Mewtwo from my history teacher, my Reshiram EX from my friend, and a random Kabuto card that happens to be in German.
Oh man the bootlegs. I have some with misspelled names. I have a fake Vulpix with reflective edges but they messed up the back colors and the font at the bottom. And the foreign language cards are always neat!
