I think this is one of the best examples of a manga that knows how to start, continue, and end at the right moment. Although the author initially wanted to focus on games in general and then, with the popularization of Magic & Wizards, shifted the focus to card duels for about a quarter of the manga, it still retains a significant artistic influence from the author and incorporates other games into the plot whenever possible. Even though it might be, erroneously, considered a "childish" manga due to its association with some kind of adaptation (which I'm not even interested in or mention in my reviews – my focus is 100% on manga) or the author's drawing style, the story is quite mature, especially and notably in the initial part of the manga, and the duels are well-done and creative.

Now, regarding fanservice, even with the focus on games, the author skillfully incorporated the sexy appeal of the female characters, including some of the cards. Enjoy the compilation.
