This deck works like this :

• Put some magic cards in the graveyard (this is why he plays Toon Table, Magical Mallet and Into the Void)
• Summon Treasure Panda (with normal summon or with Summoner Monk)
• Summon the parts of Exodia and Flamvell Guard with Panda Treasure effect (not once per turn)
• Summon Saryuja with parts of Exodia or Synchros with Flamvell Guard to draw a lot of cards
• Obtain two Dark Factory + Exodia Head, bring back other Exodia parts from the graveyard (and win by Exodia effect)

I use this same deck, except that I don't use it to win with Exodia, but to summon other monsters from the extra deck like Apollousa or Borreload Savage Dragon. I think you can use the card Tri-Wight (summon 3 normal monsters from your graveyard) to be more efficient in this case, and to have less brick hands, I added cards like Small World to get Summoner Monk in hand (because you brick a lot in this deck, and without Summoner Monk or Panda Treasure, you can't play). I added also Obliterate!!! to be more defensive in case of bad hand.
