Using Book of Taiyou, it's possible to set flip effect monsters and activate their powerful effects in main phase 1. This includes morphing jar, which allows you to draw a new hand and forces your opponent to do the same, cyber jar, which destroys all monsters and mills 5 cards which are either summoned or sent to your hand, and dice jar, which deals up to 6000 damage to your opponent (but can backfire). The rest of the deck is just removal, negation, churning through the deck, and getting powerful fusion summons, including Last Warrior From Another Planet, who prevents summons. Book of Taiyou isn't considered a flip summon, so this allows you to set cards and flip them into attack position even under his effect.
9th deck made in a progression series after drawing 48 of every set before Invasion of Chaos, but using post-errata cards and the February 2004 ban list.
