(Side deck is still in consideration)
Slow control deck with two main win conditions: Exodia the Forbidden One and Accesscode Talker and the second wincon feeding right into the first one.
Main combos are: normal summon Tour Guide From the Underworld to special Sangan from deck then link into Dharc the Dark Charmer, Gloomy for double search;
Dharc the Dark Charmer, Gloomy + summon or his effect to special from opponent's GY to link into Selene, Queen of the Master Magicians bringing back Witch of the Black Forest then link into Accesscode Talker or Unchained Abomination for a search + a good boss monster.
Destiny HERO - Destroyer Phoenix Enforcer is an awesome stall and interrupting tool and coupled with the many stall cards in the deck ( Waboku, Battle Fader, Threatening Roar, One Day of Peace. Evenly Matched ) makes slowing the game down to a pace that you can use to prolong the game for your first win condition to be achievable and/or set up enough searchers to thin the deck and easily get what you need.
DPE is wonderful alongside The Legendary Exodia Incarnate as it's immune to card effects (be careful since it's also immune to your own Waboku ) so you can effectively pop a card for free by targeting it with DPE's effect.
Instant Fusion + Millennium-Eyes Restrict is there as one-of combo protection and can be linked once you're done, working as an extender.
Battle Fader can be searched by Sangan, Witch of the Black Forest and Dharc the Dark Charmer, Gloomy but remember that doing so with the first two of them prevents you from actually using it during that turn.
Relinquished Anima + Wonder Wand can be a tricky little unexpected spot removal after using Battle Fader during your opponent's turn.
Potential cuts: Legion the Fiend Jester and White Elephant's Gift - still not sure about these two, they often feel like a brick more than anything tbh. Probably would be better if replaced by some kind of staple or handtrap.
