Roy Starfall, a teen from Equestria City is about to head home after another day of school and dueling. However, a look at one of his cards reveals a portal that sends him to a parallel world. Once there, he encounters someone looking like him, Rob Stallion. What starts as a chance encounter would soon blossom into a battle between the two lookalikes with Sunset Shimmer, Twilight, and her friends all watching it transpire. Little did anyone realize that this encounter would be the start of something much bigger than anyone would realize.

This fic also crosses over with Yu-Gi-Oh! mostly due to one character (an OC) is from a place where Equestria Girls & Yu-Gi-Oh! collide forming a dimension where Duel Monsters is more than just a card game, it's a way of life. Took a year but now it's here.
