I know on ellusionist you can get the SWE playing cards, the back design being influenced by the cover (comes in standard green, special edition black). There's also the erdnaise x madison (standard & special edition) the design being influenced by the artwork in the figure examples. The green gamblers I believe also are influenced by the expert at the card table. I know on the art of play site there is an erdnaise inspired deck. As well as there is a deck of cards on penguin magic with a standard casino backing design in white and possibly dark green if i'm not mistaken. As for collectibility? special editions are called special editions for a reason but for the novelty I reckon get the SWE deck of cards since it's artwork is supposed to mimic the book cover which in my opinion makes for a great collectible. There might be more but that's all the ones I know of, I hope this helps!
