"The Era of the Global God Cards" was a game world with cards as the main element. In it, players could summon cards of different races and attributes to fight. In addition, novels such as "I Have Unlimited Monster Cards","Denf Card Merchant", and "My Cards Have Unlimited Possibility" also have card summoning topics. You can try reading these novels to find the game content you need! I hope you like this fairy's recommendation. Muah ~๐
