Magic Ruler is a Japanese Booster Pack in the Yu-Gi-Oh! Official Card Game (OCG). It is the first Booster Pack in the OCG Series 2.
Its name comes from the high volume of Spell Cards, which are known as Magic Cards in the Japanese version and were previously known as Magic Cards in other languages.
Other languages also had a set named Magic Ruler, which was a combination of this set and the Japanese Pharaoh's Servant, but was later renamed to Spell Ruler.
This set has been reprinted in the Duelist Legacy Volume.1, which features the same cover cards "Relinquished" and "Spellbinding Circle".
This booster comes with cards which were video game-only at that time, including "High Tide Gyojin", "Whiptail Crow", "Dark Witch", "Axe of Despair", "Malevolent Nuzzler" and "Guardian of the Throne Room".

Magic Ruler contains highly sought after Spell Cards, including "Snatch Steal", "The Forceful Sentry", "Mystical Space Typhoon" and "Giant Trunade".
Each pack contained 5 cards and each box contained 30 packs.
The set contained 50 cards, or 53 in the Master Set. This comprised of:
