In Magic: The Gathering, Power Nine is a set of nine cards that were printed in the game's early core sets, consisting of Black Lotus, Ancestral Recall, Time Walk, Mox Pearl, Mox Sapphire, Mox Jet, Mox Ruby, Mox Emerald, and Timetwister.[1] These nine cards were printed in the first sets of Magic: The Gathering, starting in 1993. They are considered among the most powerful cards in the game.[2] Owing to their power, they were banned from being played in most competitive settings.
