There is a wonderful mod by js303 (NoScope1080) called "Fancy Decks", it changes the texture of standard decks in Balatro (red deck, blue deck, yellow deck etc.) for a very pretty back of some real life cardboard cards.
Sadly, in its current state, it is outdated and has conflicts with many other texture mods. So I've tried to make it comfortable to use in game again. Problem is - I have zero knowledge in lua coding. So, I've picked Malverk texture manager and tried to use Luna's Enhancements mod as a base. And thanks to @smoky ravine's big help, this mod is fully working now.
Malverk is required
