I think I just went into diabetic shock...
Indices on the wrong corners.
All cards of the same value have the same image.
Way too low of a goal for a good manufacturer.
There's also the values sitting in the suits, though that's not the end of the world. It's the least of this deck's faux pas.
It's clear that this designer has never designed a deck before. I'm almost forced to ask if they've ever used a pack of cards before, because this deck doesn't look even close to any deck I've ever used. Yes, that sounds harsh, but while there's some decent artwork here, there's no attention paid to the standard design elements that make up a functional pack of cards. It's one thing to break a design rule for a reason, another because you just didn't know the rules exist.
