It's a different world based on cards. Whether it's powerful transcendent creatures, or divine weapons that contain divine power, or even things like hurricanes, thunder, lightning, and fire, they can all be sealed by cards. A person who has mastered the ability to control these cards is called a summoner. You Chu, who crossed over with a certain card game system, was faced with the fate of being sacrificed by the villain as soon as he opened his eyes, and the only thing that could save him was the opportunity to draw a card that was given only once by the system. But it doesn't matter, everything about a true summoner is inevitable, even gacha can be created! Single Draw Miracle! [There are already 10,000 works "I play cards in the duel city"]
