This is my improved build. I made some deck changes to play less garnets. Allure of darkness is really powerful in this deck. You have to use three copies by banishing exodia pieces or summoner monk. Then you can use pot of acquisitiveness to shuffle your banished monsters back into the deck and draw one. Magicians souls can pop the cursed bamboo swords to draw one or two cards then you can use the effect of cursed bamboo sword to search golden or original bamboo sword. You can generate a massive amount of spellcounters by the bamboo engine and also the toon engine. Spell power grasp is also really good to generate even more spell counters. Here the card by card:
5x Pieces of Exodia: this is your primary and only win condition
3x Royal Magical Library: you always wanna see this card. Wouldn't cut
1x Summoner Monk: gets you access into library. Can discard cursed bamboo sword to generate advantage and also can be banished by allure of darkness
1x Anchamoufrite: no extra deck, this card acts like upstart
1x Magicians Souls: can destroy up to two cards and draw the same amount. Really good card, can destroy cursed bamboo sword and toon-world. You wanna destroy two copies of cursed bamboo sword
1x Illusion of Chaos: gets you access into souls and also makes souls life
3x Cursed Bamboo Sword: gets you access to golden bamboo sword and original bamboo sword. This card can bounce back one other cursed or original bamboo sword to hand to generate spellcounters but this is once per turn.
3x Golden Bamboo Sword: basically pot of greed
1x Original Bamboo Sword: makes golden bamboo sword life as well as cursed bamboo sword. You can send this card to your graveyard to equip one cursed bamboo sword from deck, but this doesn't generate a spellcounter. Nevertheless you have to do this so you don't draw into cursed bamboo sword
1x Foolish Burial Goods: to get cursed bamboo sword in the graveyard and search. This card is once per turn, so only one copy of it
3x Toon Table of Contents: this card can search itself and generates 4 spellcounters
1x Toon-World: Just fodder, one copy is fine
3x Magical Mallet: to shuffle back cards you don't need at the moment or to shuffle back exodia pieces
3x Allure of Darkness: basically pot of greed if you banish exodia pieces or summoner monk
1x Pot of Acquisitivness: allows you to shuffle 3 banished exodia pieces in the deck and draw one
1x Double Summon: sometimes you need a second library
1x Piri-Reis Map: you have to activate it at the start of main phase 1, gets you into library. In my former build I played 3 copies. This wasn't good enough because you don't wanna draw into the map. It's like if you have it, you activate it. But If you can't it's useless. I think 5 chances to get librarys is enough
1x Wonder Wand: this card is alwyas for magicians souls. Sometimes you have like 4 exodia pieces and only wonder wand and library on the field, then you can risk it
1x Top Share: this card can get you access into everything
2x Spell Power Grasp: searches itself and generates 2 spellcounters
1x Into the Void
1x Upstart Goblin
1x One Day of Peace
