It's got more to do with the "intriguing" way that some of D&D's products have been marketed in the past.
So, they fixed the "more than one deck" glitch.
Supposedly, they'll be going over the orders and only letting those on the mailing list get a pack. Only time will tell if any of this is to be believed, since it does sound a wee bit far-fetched.
As far as cardistry, they're great.
As far as a great selection of magic in their shop, particularly in print, they're hard to beat.
As far as their cards, the most exciting thing I've seen them put out in perhaps a year or two are two reprint decks. That's it. To me, they'd be a better company if they just got out of the cards business.
BTW: you do realize what this whole Deckstarter thing is supposed to be, right? It's D&D's answer to Kickstarter - they want to start making other people's decks. To be more accurate, they're a mix of Kickstarter and HOPC. Would you want to make a deck with these guys?
On a positive note, it's one way to insure their deck designs are more interesting - let other people design them!
