The main thing this deck is to do, in order to get out the 'The Unstoppable Exodia Incarnate' is pitch the cards to the graveyard (so youre not having to keep them in hand and especially not wasting your normal summon for turn on them either.) and use "Magicalized Fusion" to get the big boss out, or if youre feeling up to it, and normal summoning a piece just for fun and using it to get 'The Legendary Exodia Incarnate' would be fun too, but only IF NEEDED as another body to hit with, should you do that. I'd even use Legendary Exodia Incarnate as Timaeus fodder to be honest.
Shining Sarc and Dark Magician go hand-in-hand, as both effects can be used simultaneously, use Shining Sarc to get Dark Magicain. Then, use Dark Magician's effect to special summon from hand, if you do happen to have 'Dark Magical Circle' on field, 'Dark Magician The Magician of Black Magic' DOES activate the effect of being able to banish a card as per it's effect saying, 'This card's name becomes "Dark Magician" while on the field.' So you can even possibly utilize Dark Magic Attack in too. Blue Dragon Summoner and Summoner's Wand are in here to help possibly even get Exodia Pieces for a potential win, if you can pull it off.
Contract of Exodia, Exodia Necross, and The Legendary Exodia Incarnate are mainly just possibilities, as you'll mainly put the Exodia pieces into the graveyard (as mentioned above) to utilize Magicalized Fuison. The "Raging Hellfire - Exodd Flame" is also a possibility to utilize The Legendary Exodia Incarnate and Exodia Necross, as youre able to shuffle all 5 pieces form the Banishment BACK into the deck.
Another fun little gimmick that is present in this deck is a fun 'loop'. This loop is using 'Obliterate!' to send Dark Magician the Magician of Black Magic back to hand to pitch an Exodia piece then summoning DMtMoBM back from your hand if Shining Sarc is on the field.
A possible tech I may add is 'Dark Magician the Dragon Knight', as it will protect your spells/traps, so then youre able to keep your back row safer.
Any suggestions and/or discussions will be fun to have on this theory deck!
