I don't know if there's a thread about this yet or not, but recently I picked up the Master Collection of uncut sheets from Theory11. When the sheets arrived, I noticed that the Black Artisan looked quite a bit different from the deck I have. The Ace of Spades has a different date on it (04-13) instead of (11-12), the back of the card has the same changes as the White Artisan and the big different, that grabbed my eye first, is that the metallic ink is silver instead of gold (see photos).
I emailed them about it and apparently when they were doing a second print run, they went ahead with adjusts to improve the design (less green looking and thinner borders).
Anyone actually have a deck of these yet? It's also suppose to have that newer date on the seal as well. Personally, I like the newer version of the Black Artisan, but if that's what they're shipping out when people order, I'd wish they'd put some kind of disclaimer on their site. It's noticeable different.
