Please note that this is experimental, test with a copied folder of whatever creator you want to sort items of.
I have made and tested this by myself, but i cant ask you to take the risks without caution, so i will say, use/test at your own risk. but i truly i hope this helps, i also struggle with duplicates, so please test if the cards work after the process, on my end, it seemed okay but i would like more "testing" before calling it a final product.
This removes duplicate cards(checks hash) overall and renames the rest based on the meta data available, it works only inside of the folder you extract the files into, run the bat file and it will do the rest.

Test.
1. create a copy of the creator/folder you want to sort.
2. Extract the contents of the zip file into that folder as it is.
3. Search for the .bat file.
4. Run it.
5. wait for results.
Always test before actual use, i cannot 100% certify of accuracy when it comes to the file renaming thing due to metadata issues when files are saved from the internet etc..
