Become Invincible in the Card World Starting from Shadow Mantis

In this world where cards are supreme, all power comes from cards. The character card summons creatures to fight for you, the skill card gives you the power to change the clouds and rain, the prop card changes everything, the vehicle card gallops around the world, the building card uproots the castle and fortress, and the rule card rewrites the world. Shadow Mantis, Shadow Windbreaker, Demon Sword Fairy, Mobile Fortress, Magic Castle... But don't panic. While others were still fighting for a blue card, An Yan, who came through time with a card drawing system, had already begun planning the synthesis route of golden cards. There are various evil ways of playing such as land farming flow, snowball flow, and bluffing flow. "Use a wheelchair to open a blocked path for the flow of technology." An Yan said. "Fate will not favor anyone because of a gold card. He doesn't dare because I will blow him up."
