I did take a look at the card templates you sent me and they weren't seriously usable. They were half the size and had inconsistent proportions, inconsistent positions, and inconsistent fill patterns (read: clone brush usage). They weren't even layered. There's no way to use them that doesn't involve scrapping all but one and starting from scratch, but at a smaller resolution, with an unremovable price coin icon, and with no obvious benefits to make up for it.
I am sympathetic to the argument that I should be using the colors people are most familiar with from other templates, even though those have been warped by printing and later scanning, rather than the ones that I think are most likely to be canonical, but using those particular images is not the way to get that result.
I will be looking at the inline icons some more. I know official cards are not consistent about their sizing, but because this is a program I do actually need a consistent rule, so I expect I'll look at a bunch of Empires cards (because they use the most updated style) and figure out what looks right from there. The most important bit is to get the $ symbol in "+$" to turn into a coin icon and the + to be drawn in bold, but resizing can happen while I'm looking at that part of the code too.
