Exodia Deck

You can switch Cardcar D with Cyber Valley for more stalling.

Summon either Sangan or Witch Of The Black Forest, use Dark Hole then search for one of the pieces.

Activate Allure Of Darkness at all costs, then banish either Sangan or Witch (you need Battle Fader for stalling).

Use Magical Mallet to get rid of cards you find unnecessary at any specific time during the duel.

Gold Sarcophagus can be used to either slim down the deck so you draw the pieces faster (in this case you banish any other monster that's not an Exodia piece) OR you can banish a piece of Exodia, use Burial From A Different Dimension to send it to your GY (another piece must be face up on the field at this given time), then use Dark Hole or Torrential Tribute to send the face up Exodia piece to the GY. Once this step is complete, you can activate Dark Factory Of Mass Production and retrieve both pieces. ONLY go for second route if you wanna retrieve the piece banished by the Sarcophagus the SAME turn it is banished. I'd do this if only one piece is remaining.
