The Bad Ink deck is so close to being a "perfect" deck for me. I love the style. I love the clear damage markings. I love the clarity of the text. I love that it's plastic. I love the magnetic box. But for me, it's not yet a perfect deck. But it's sooo close!

Suits next to the numbers represented larger. The illustrations are really cool for me, but they're busy enough that for some opponents, it's hard to make out what suit I just flipped from across the board
Linen finish, like on the Retro Fate deck, to make the cards less slippery and more rugged, as baggined mentions above.
An illustration on the back of the cards, instead of "M2E".
