They don't sell the P5 Tarot Deck that this mod sources from anymore, but they do have other decks, including a very cool looking P5R Tycoon deck. Go check 'em out!
This mod is my take on the English Calling Cards mod idea. A while ago, I had bought a Persona 5 Tarot Deck from an Etsy store called ArtisticsMeasure. It's a good deck, high-quality, comes with major and minor arcana, AND.... a handful of bonus cards: the Phantom Thieves' calling cards. All of the calling cards are included, even the 3rd semester palace ruler's. It's a good bonus, and it sure came in handy here. And so I used my shoddy printer and scanned them, and modded them in-game.
All the calling cards are replaced, including the 3rd semester palace ruler (not saying his name because spoilers). I also put them in the thieves den. Have fun zooming on on the crusty scan artifacts.
By the way, yes, I know the cards use Earwig Factory as the font. No, I don't care. As far as uses of Earwig Factory go, ArtisticsMeasure used it pretty well here, I think. If you don't like it, make your own English Calling Cards mod.
I might update this mod later on with higher-quality scans. No guarantee though.
