A name given by players of
Magic: The Gathering to nine incredibly rare cards printed primarily in Alpha, Beta, and Unlimited known as Ancestral Recall, Black Lotus, Mox Emerald, Mox
Jet, Mox
Pearl, Mox Ruby, Mox Sapphire, Timetwister and
Time Walk. These cards are widely considered the most powerful cards in the game, but are however illegal in every tournament format except for Vintage in which they are Restricted and therefore cannot contain more than one copy. Common attempts by
Magic: The Gathering creators have been made to replicate the abilities possessed by Power Nine cards, but for a larger price to pay and/or for less effect- which further contributes to why these cards are considered so valuable. The
five mana-producing Mox cards belonging to the Power Nine are commonly referred to as ‘The Moxen’ alongside the four other Power Nine. Although more ‘Mox’ cards were created, as were more additional turn spells in alignment with ‘
Time Walk’, no others were
later considered additional members of The Power Nine.
