Card Master, I Can Use Yu-Gi-Oh Summon

The Hell dungeon has been cleared again! His profession is again... Card master? Travel into a world dominated by game copies and awaken the profession of card master. I originally thought I was a dark horse from across the world, but I found out that I was really a dark horse. Is the copy too difficult? I directly summoned the Dark Master and passed the level directly. College competition? 1V1 is still a group fight. When there is a disaster in the world, I just spread the beans and become an army. What should you do? What did you say? Is there a restraint relationship in the profession? Sorry, I was able to make Holy Shield. Too many enemies? Sorry, I have the death deck buster virus. "Great Sage! Take away your magical powers!"
