ME TOO, actually! I have just returned to my personal projects. For this I am doing a palette, transparency, and animation update for end of July. After that I will order a proof and post up my results in a devlog. If they feel right in the real world I will look thru if it is worth it to produce and sell, or build a campaign to get them out there.
Awesome news! I've been searching for some nice pixel art playing cards, and there have been some funded with kickstarter, but truthfully, I find yours a lot better. Best of luck if you decide to go ahead with it, and do let us know!
