It's been two years since the discovery of the human world/pony world(depending on which one you are in) and consequently the card game Duel Monsters. Princess Twilight Sparkle sees great potential in this game for harmony, so that when she sees that it isn't as popular in Equestria she decides to use the upcoming anniversary of the discovery as an excuse for a tournament to help popularize the game. Only the ponies she wants to represent Equestria with her don't know how to play.

Thanks to my friends for letting me use their personalities with a large amount of tweaking.

(All duels in this are based on actual test duels.)
