I, too, am very disappointed in the deck. While Robert Place's artwork continues to enchant, the cards are too large to shuffle and, as Mimers says, they are so sticky that prying them apart easily damages the card stock - and this problem is compounded by painfully sharp square corners, which were already separating in my deck merely from the pressure of the shrink-wrap.
This deck strikes me more as an art deck than a pack for daily reading or heavy use. With fanning powder, it might be possible to shuffle it using a "mixing" technique, but the corners are so sharply squared that the cards will be damaged just by bumping against one another.
If circumstances permit it, in the future I hope that another version of the deck will be printed, either in a smaller size or on sturdier stock, with rounded corners and a more matte finish.
