Seems Pretty Useful – Deckromancy® Trading Card Maker - Craft of the Deckromancer™ with Animated GIF / APNG foil Lite Review

As far as designing cards goes, this is probably the easiest way to do it. It looks like you could do a lot of cool stuff with it, but I don't really know how to do anything outside of arranging the various parts. I wish that they'd be more clear about the difference between the paid app and the free app, though. I had to do a lot of searching to figure it out, and I'm STILL not sure. It seems the main difference is the ability to use high-res images, but that might just be the difference between the PC/Mac versions.
