This is a mod that will change some card art to badly drawn art, courtesy of 4chan.

You install this the same way you do any other mod:
-Extract the rar
-Go into the install folder
-Copy 0000
-Go to C:\Program Files (x86)\Steam\steamapps\common\Yu-Gi-Oh!  Master Duel\LocalData\XXXXXXXX\
-The XXXXXXXX will be different for you
-Paste the 0000 folder here, and replace the files
-Copy AssetBundle from the install folder
-Go to C:\Program Files (x86)\Steam\steamapps\common\Yu-Gi-Oh!  Master Duel\masterduel_Data\StreamingAssets
-Paste the AssetBundle folder here, and replace the files
-You are done

To uninstall, go to the uninstall folder, and follow the same steps.
NOTE: The uninstall folder contains OCG art. So Spirit Message "I" well be "E" instead, and Skill Drain will have horns, etc.
If you want to properly back up your files, compare them with the mod and back up accordingly.
