The 648 and 649 Decks (Ruby and Sapphire): These were released on 28 March 2003
White of course has lots of great oppressive cards like Drannith Magistrate, Spirit of the Labyrinth, Archon of Emeria, Aven Mindcensor, High Noon, etc
Throughout the series, he meets his eventual rival, Seto Kaiba, who he defeats in their first battle at school and during Death-T, and meets other wielders of the Millennium Items, including Shadi and Dark Bakura
In modern SV sets you see rough guides like a Double Rare around 1 in 5 packs, an Illustration Rare around 1 in 12, an Ultra Rare around 1 in 15, a Special Illustration Rare around 1 in 90, and Hyper Rares in the 1 in 300 to 700 range, and any one specific card runs far longer than its rarity band suggests
A nice grip to make the deck better manageable
