War of the Spark is a Magic: The Gathering set famous for turning planeswalker cards into permanents that can be attacked and killed like creatures, a major rules shift that redefined how the format's most powerful card type is played. Set during Nicol Bolas's invasion of Ravnica, the set features nearly the entire cast of Magic's planeswalkers converging in one climactic war. Its uncommon planeswalkers made the mechanic accessible at every level of constructed and limited play.
