It's a relatively normal day in Canterlot. The sun is shining; the birds are singing!; and somebody somewhere just spent a good chunk of change on the latest Duel Disk model. Yes, Duel Monsters has become quite the phenomenon, and the Canterlot scene is beginning to develop quite nicely. The local card shop has even decided to hold a beginner's tournament to help introduce new players into the game!

So; what happens when a few, questionably normal magic-infused high schoolers take up an interest in a game that's never really mixed well with magic to begin with? Naturally: nothing good! It's up to them and their new companion: a self-proclaimed Duel Monsters veteran named Onyx -- who has decided to help them learn the basics of the complex game -- to discover the consequences of the cards' newfound hidden powers.

It's a good thing he's a pretty understanding guy. Right?

[Crossover] with Yu-Gi-Oh! based on the EQG universe, but with several fundamental differences -- hence the [Human] and [Alternative Universe] tags to account for canonical discrepancies and the sudden prevalence of children's card games. Additional character or genre tags may be added as necessary. "Duel Monsters" utilizes the updated Yu-Gi-Oh! Master Rule 4 established in July 2017.
