Do you know how to cheat the cards? Because I reall don't want to spend hours just to get all the cards.The game has mild NTR.
Also, there's a trading card collecting minigame where you spend an emerald to get a random card.
The interaction takes about 4-5 seconds each and will run you about ~1000 emeralds to get every unique card (I currently, have spent ~950 and am still at 109/110 cards.)
I HIGHLY reccommend you either cheat your emeralds or the rarest cards and not spend hours trying to collect stupid cards.
