If they don't tell you it is World Championship and not a tournament legal/real card you can return it under ebay/paypal's buyer protection policy with a significantly not as described claim. So, it can use up your money for a bit, but for all the harm it is still doing some good as it causes some sellers to lower the price of their real Luxray if they are not knowledgeable. For example I just got a Luxray GL Lv. X (Confirmed by seller as being not WC, so if it is he will ...use your imagination...) for $23 shipped with an additional random Lv. X. Besides, I can point out a WC Lv. X card a mile away, the blank silver border and signature are dead giveaway's.
Edit: And on a side note, since this is an ebay thread (mod's can slap me if I can't do this) there is currently an Uxie Lv. X (Real) for $28.50 shipped (buy-it-now) on ebay. Just a heads up to anyone that isn't broke like me XD.
