Yugioh Battle of the Emperors

You start off being taught by a Man name Jenson Dolrich. He says that you have shown much promise in the duel world so he will give you a chance to prove yourself as a Spellcaster.

You assume he meant Spellcaster deck user. You either nod or correct him on your deck, but he ignores you. Instead he holds out three cards. Dark magician, Endymion the Master Magician, and Chaos Sorcerer.

"Choose," he commands.

Since it is a free card you couldn't help but pick one. Little did you know that the card of your choice sends you to the shadow realm. Your fate is sealed and you must find your way back to Earth.
