A World Where Dueling Is Everything

A rare masterpiece under the card theme, the content is mainly about the duel process, coupled with the expression of emotions, the design behind it is very creative. The protagonist strives to become the Duel King (to save those he holds dear), so welcome to a world where duelistism is paramount.

Suddenly I found that I haven't given a rating after reading it for a long time [palm][palm], I must give it a five-star rating, I hope the author will not stop updating it [sending heartfelt wishes]👍

I have a question: Since the spirit behind the back is on the scene, does the spirit behind the back belong to the category of summoned objects?
