The New Ruler booster is a Japanese Booster Pack in the Yu-Gi-Oh! Official Card Game (OCG). It is the first Booster Pack in the OCG Series 3. This is the first Booster Pack to use three letter abbreviations for the set ID and use the order number, rather than a shorthand of the set's name. This set also marked the first use of the "World Standard" format within the OCG, matching their design and layout to that of the international Yu-Gi-Oh! Trading Card Game's format.
It contains cards like "Helpoemer" and "Coffin Seller", the first appearance of the "Gravekeeper's" monsters, many cards used by Dark Marik, in the manga, and an Ultimate Rare reprint of "Red-Eyes Black Dragon".
Each pack contains 5 cards and each box contains 30 packs.

- 5 Secret Rares
