Instructions
Play through the story mode of "Yu-Gi-Oh! Duelists of the Roses" until you reach the duel with Jasper Dice Tudor.
Begin the duel against Tudor and summon your creature cards in attack mode. This way you will be able to attack and destroy his five pieces of Exodia as soon as they are summoned to the battlefield.
Wait for Tudor to begin placing his pieces of Exodia to the battlefield. This shouldn't take long as his deck revolves entirely around getting the five pieces of Exodia on the battlefield.
Order your monsters to attack any piece of Exodia that Tudor summons to the battlefield. As a general rule of thumb, you should attack the pieces of Exodia as soon as they are summoned to the battlefield. This will prevent him from getting all five pieces of Exodia out, subsequently causing you to lose the duel.
Continue attacking Tudor's pieces of Exodia until you have sent one of each to the card graveyard. These include the Left Arm of the Forbidden One, the Right Arm of the Forbidden One, the Left Leg of the Forbidden One, the Right Leg of the Forbidden One and Exodia's Head.
Defeat Tudor by reducing his life points to zero. You can do this by attacking his life points -- instead of his monsters -- directly with your monsters.
Spin the slot reel -- to which you are automatically taken -- at the end of the duel. You will have a random chance to win any cards that were put into Tudor's card graveyard, including the five pieces of Exodia.
