The sheet is an obvious misprint because the cards have Pokemon card backs. See the actual auction here . See the image on the auction page here . The sheet is obviously curled up. 67 are different.
All cards have new, never before seen artwork.
There are two weird half-sized Magic cards on the sheet, which I don't know how did it happen. You can also see there are the usual color reference bar on the edges of the sheet. Whatever happened to waiting patiently before a new set comes out. We all know they release too many sets as it is. There are many duplicate cards on it.
