Polygon has compiled a list of the ten fastest card bans in Magic: The Gathering's history, highlighting cards pulled from play soon after release when they proved too powerful for their format. Rather than ranking the most broken cards overall, the list focuses on those that gave Wizards of the Coast the least time to react, from early design mistakes to modern cards that were quickly exploited in unintended ways.

Entries include Tolarian Academy, banned 50 days after Urza's Saga for enabling absurdly fast combo kills; Oko, Thief of Crowns, banned 45 days after Throne of Eldraine despite appearing in nearly 70% of competitive decks; and Underworld Breach, also banned within 45 days after combo players turned its graveyard recursion into an explosive engine with cards like Grapeshot and Mox Amber.
