Is there a code for labyrinth wall?? i checked my card i fond out it was a misprint i hadnt got a code

This card, like gate guardian and the three cards to make him do not have card numbers they are special rare cards that are treated as card # 0's

and your card isn't a misprint, mine nor my friends' labrinth wall cards have them either, i think they didn't print a number on some of the cards. they are re-printing those cards that didn't get serial numbers in the new packs
