Could you please use the Template:TradingCard2 in the future on trading card pages, and not Template:TradingCard? The second is pretty old and in the process of being phased out. I saw you still used the old template on the newly created pages. Thanks in advance!
I just created this page Seeds of Chaos - Alexia, you can use that as an example. The newer is a lot more simple as you don't have to add names of the files anymore.
The only thing you need to keep in mind with that template, is that with games with 10 or more trading cards, Card Artwork images get an extra 0 in the name. So for example: STAR WARS Battlefront II Artwork 09.jpg instead of the usual STAR WARS Battlefront II Artwork 9.jpg. That's pretty much it, the rest is straightforward. If you need help with explaining more, feel free to ask!
I now applied it to STAR WARS Battlefront II - General Grievous. It doesn't pick up the cards, but that's because the cards have their names wrong. They have a zero in front of the number at the end, which is incorrect. Only with 10 or more cards, and *only* for the Card Artwork. Cards never need to include that zero :)
The part about Template:TradingCard2's Artwork numbering is insane. I've now reworked the template so that regardless of the number of cards in the set it always just tries to find a file without the zero, but failing that, displays the file with the zero prefix (or a broken link to it, if even that one does not exist).
So @ZeroOne, does that mean the zero is never needed anymore? The creator of the template said to me that wasn't possible at all. I never was a fan of it as it was confusing, especially to new users. If so, you made me a very happy man :)
Indeed, if I managed to implement it correctly on the first try, the zero shouldn't be needed ever again. Also, no need to rename the existing images with the zero, just let them be -- or at least don't do it manually, have someone create a bot to do it. (Or better yet, this would be a great opportunity to learn some programming language and create the bot by yourself!)
I already have a bot since 2014 :P User:Kennybot. But as far as I know, renaming pages isn't one of the things the bot can do. But lets move this conversation to either mine or your message wall, now we're spamming MugenSpider on his wall.
