Deckbuilder, the way you say it will be like a ccg to me just doesn't fit, as the promo cards are only promo exclusive for so long until they are printed in a set for everyone. I've never had trouble finding pictures or information, as board game geek has a lot of them posted on their site, and a quick search of mage wars promos on ebay pulls up pictures enough for me to make a hand written proxy if i want to play with it. The only edge people get is to test it early, and as shadow said, it is like a testing phase for those cards, so even if you get a promo, it might not be that strong when it comes out.
