Heyo! I noticed you said this page is still a WIP since I had the "wrong emoticon files". However, I've done exactly what this page told me. How are you able to tell whether or not the files are wrong? Because I'm not exactly sure how I'm supposed to fix it.
I can tell they are wrong since they're tiny with huge blocks of white around them, being 360x360. While the actual emoticons are 54x54.
Not really sure about that suggested method, but me myself search the elements of the page. The correct one is right below the incorrect 360x360 (make sure it's saved a .png though as it defaults to .html by default). Not sure of an easier way.
If you upload a properly named artwork it will appear automatically on any templates using TradingCard2. You don't need to modify them (note that the result of the Over the Dream cards before and after your edits is exactly the same, aswell as for the Nuclear Throne ones that you've modified).
I saw your profile update, but I don't really know what you're upset about. The only thing I can see about December 9th is some additional trade restrictions if you're not using their mobile authentication app. That seems annoying, but... eh.
No smartphone so "3 day period that items hold", which I doubt most people would want, so if getting doubles, need to use market to change them around rather than trade - generally the worst option in those cases... :/
