I've looked over them, but I can't figure out what these cards are. I know that they are yugioh related and I'm assuming that they are fakes, since they look nothing like regular yugioh cards, but given the number of them included I'm not really sure. (Around 250-300 included from the size of the stack, but I haven't counted them.)
I'd identify them myself, but I'm busy looking up set info and prices for some of the other cards included, mainly pokemon and naruto.
Here's the pics of them. Crap quality since it's taken with my ds camera.
