As a quick FYI, artwork is complete on Aurum and is currently at USPCC being reviewed and getting ready for proofs. To answer Don's question above, yes all of the cards feature metallic inks. Spot cards have gold or purple along with a near-black metallic, and court cards will feature a bit of all three. They should be pretty shimmery and interesting. The subtle continuous line in the background of the faces will be normal black ink (though very light in tone). That line on the back will be metallic over a solid purple field.
The tuck case will also have some interesting features, which I will share more about later. Some things need to remain secret for a while, but if they can coordinate it properly it will be a special & unique thing...
Also, just in case you didn't see it, there is a little Facebook giveaway happening right now, so go check that out. You might win this sample deck:
