Imo MTG has written the rules of card treatment for at least western made card games. Full art, Alternate art, Foiling. These make cards collectible and therefore push packs. Lorcana and Flesh and blood have coopted these concepts and made them more special and less moneyhungry over the top fomo BS. Stick with the basics, dont make the cards look cheap, and make the game fun. Easier said than done I know but still.
