There are two versions of Pullusic?
If you are a collector that must have every card printed, you will need to acquire both versions of the promo character, Pullusic. The art, provided by Clive Barker himself, and the game information are the same on both versions. There is simply additional content in the copyright section of the card and has no effect during gameplay.
The “1997 Dragon Con” version was given away to demo participants at Dragon Con in, you guessed it, 1997. The “1997 Dragon Con” information is omitted from the standard version that was distributed directly through the ZI Games website. If you mailed in your information, they sent you a copy of the standard version. Imajica CCG Demo Representatives / Tournament Directors distributed some as well.
Since both versions are promos, both versions are difficult to locate.
Good luck in your search!
