Get Witch Of the Black Forest and/or Sangan, all five pieces of Exodia, Monster Reborn, and Magician of Faith. Use Witch Of The Black Forest and/or Sangan in defense mode and let them die. Chose the pieces of Exodia to draw to your hand. Use Monster Reborn to get one of them back. Repeat the defense part. Use Magician of Faith to get Monster Reborn back and Monster Reborn to get Witch Of The Black Forest and/or Sangan back and repeat the step again. You should now have deliberately drawn at least three pieces of Exodia.

Have Swords Of Revealing Light, Pot Of Greed, and some Morphing Jars. When you have at least two pieces, use Swords Of Revealing Light, and on your next turn, use Pot Of Greed. If you get any pieces on your next turn, when you press A, press B then press R. This should help you get Exodia faster.
