*Yu-Gi-Oh! Crossover*

Duel monsters. The now-popular card game started out as a chaotic idea by the Spirit of Chaos, Discord, himself— then changed into Equestria's most powerful weapon after two alicorn princesses and the everyday ponies liked this idea. Griffons, changelings, and even dragons adapted to this game. Playing for entertainment, decisions, and of course combat.

The Princesses and Element Bearers protected Equestria from Changelings, Tyrants, and a magic sucking centaur by playing this game.

Now they are at peace, but new evil will soon arrive.
