Wizards of the Coast accidently printed a few error cards in the Jungle set. The most common of these cards are some Holofoils that don't have the expansion symbol on them. like the card pictured. Other errors include misprinted words, the HP at the top missing, and some color variations. Many of these cards can be worth much more than the correct card, so if you get one of these, don't throw it away or trade it because it could be worth money!
