They look very, very similar to the Hudes deck. In fact, so similar that I've a nasty feeling it might be the Hudes, worked-over to escape copyright. Has anyone told Susan Hudes?
I put the cards side by side (thanks for the cap Glass Owl!)

I have to admit, I don't see any similarity at all!
Sadly, at this point whenever I see a great deck in a tv show I assume it's a one-off, incomplete prop. Which is a shame because I'd definitely be interested in this deck, "The Cloak" and all!
