Just wanted to post with my personal related wishes/thoughts!
I don't think decks by Paulina Cassidy or Lisa Hunt (both have decks published under USGames, which I'm sticking to here) would do well in tin size. Much, much too small. In fact I'm shocked that the Thoth does so well in its pocket form; all those small details really would be irksome to try and read in any smaller size but standard.
I would love a pocket Deviant Moon. It's long, so I'm not sure how much squishing would occur in image resizing, but it's bold with lots of BIG and contrasting detail, and the Borderless Edition, while lovely, is really quite big and hard (for my pygmy hands) to shuffle.
I also second the Japaridze, though it's new!
Lastly I think that any and all of Ciro's decks possible would be exquisite in pocket size. His decks are perennial favorites and though detailed, are crisp, bold, and colorful enough to be read seamlessly in smaller form.
