Hmm, I don't have them all, but I have a sizable collection. But I don't buy them.
At least not lately. I bought 14 cases of WotDQ (you heard me), but that was the last big purchase. I bought a couple hundred last January (2007, not last month), but they were cheap singles. Between already having a large collection, the price increase, eBay fee increases combined with 'crap rares' (I would sell the rares to pay for the cases), and a player who 'collects them all' I haven't felt the need to drop the cash on them.
