Consider making "Jackie O." as "Jackie Kennedy" instead - she didn't become an Onassis until some time after her husband's assassination.
Strangely, I don't think any of us even considered that point. Of course, she was Jacqueline Kennedy Onassis when she died. I'm not sure of the protocol when it comes to naming zombies, but I'm tending to agree with you.
Consider in the indices using smaller pips and bolder letters/number. Value is usually the first-most important of the two in card games - a standard index shows a pip that's half the size of the value.
Good design note. I'll relay it to the design guys.
I really have to ask - why zombies? It's rapidly become the most tired theme for a custom deck of playing cards. At present, just under the Bicycle brand, USPC offers in their current product line two decks directly themed on zombies and four that are indirectly so themed. That right there should be a sign that's it's overdone and not simply becoming overdone - it's ALL the way there. I won't even bother with the nigh-countless KS decks that are zombie-themed.
I guess you won't be supporting our CTHULHU PRESIDENTS and STEAMPUNK PRESIDENTS decks, then.
But yes---zombies are WAY played out. I agree. However, I suspect the artist may have had more to say than just, "BRAINSS!!!" I gave my thoughts on the UC forum, but they are just my thoughts. They are no more valid than any others when it comes to interpreting art.
