My understanding (from reading) is that they have done away with the Black Card membership. Perhaps someone with better "insider" knowledge will be able to help more.
This appears to be true. The club suffered some major flaws that made it not worth the price of admission.
There's one deck, the Artifice Black Club deck, that used to be available only to club members. They're now selling it for $12 a pack to anyone who wants it.
http://www.ellusionist.com/black-club-artifice-deck.htmlTheir other Black Club exclusive deck, the Gold Artifice deck, doesn't appear in a search on their site. It's possible, though unlikely, that they sold out of them to club members - they were restricted at one point as to how many they could purchase, but it's possible that the restriction was at some point lifted. Even premium decks no longer in stock like the Black Ghost First Edition appear in a search on the site, though are listed as sold out, but not the Gold Artifice. Perhaps they're holding on to what's left as some kind of future enticement/premium, possibly to be made available at Black Friday/Christmas?
