I remember that big Magic Engine thread for this, but unfortunately I never got to see this stuff when it was fresh. Anyways I would have probably thought this was real too, but what would have thrown me off was the fact you could play as Simon (although the screenshot edits were well done and really fit in with the game, so I would have still believed it), the fact that it's labeled "SPECIAL VERSION" (seems like Japanese would have said something else), and how the text for "SPECIAL VERSION" doesn't quite fit in. Also if I did see this back then, I would have probably been a nerd and read the back of the HuCard and use translators to figure out if it said anything about Dracula X. Other than that, I would have totally believed it because the story sounds believable like other PCE cases and the photo editing was really well done. By the way, what's with the $20 shipping!? Haha.
The Japanese actually labelled a series of promo versions of HuCards as "SPECIAL VERSION" and on each one, the logo across the HuCard actually looks phonier than the one I put together. Take a look, this guys selling at least 4 of them-
http://stores.ebay.com/THE-DREAM-STARS_W0QQssPageNameZstrkQ3amefsQ3amesstQQtZkmAs for the back of the HuCard, most games use a generic template and I scanned my Salamander HuCard so that it was exactly how a Drac X HuCard would look(Konami).
The $20 shipping for something that would require $0.75 postage is another classic scam these guys pull. Either listing a ridiculously high shipping price with a low bid amount to avoid eBay fees or the type who don't specify an amount, but later invoice you for something huge(again, against eBay's rules) and will leave you negative feedback if you don't pay.
This happens to me all the time where an auction lists $3 - $5 shipping within the U.S., but will ship worldwide. So I buy it and then they tell me that it'll cost $15 to ship and of course the postage turns out to be $3.95. Again, if you leave appropriate feedback you get retalitory negative feedback because eBay only cares about $ from sellers.
When it comes to over the top hyping and outright lying in descriptions, I remember back around the time eBay was created and the only place online I knew about for Turbo trading & discussion was the Turbo Compendium(back when I was using my trusty Sega Netlink).
Adol used to sell a bunch of stuff there before switching to eBay. And he would sell 'factory sealed' PCE games that didn't have spines. When he was called on it, his angry explanation was that "spine cards aren't used in France", so of course when these Japanese games went to retail in that country, logically they wouldn't have had spine cards.
So basically this guy was just shrink wrapping up a bunch of incomplete used games and selling them as brand new without any pictures(before cheap scanners and digital cameras).
And when he did finally switch to eBay, his descriptions were always "super ultra rare!!!... one of a kind!!!... never found complete... etc..."
