702.195. Storied

Storied is a static ability. It means “Any time you control three or more permanents that are artifacts, Sagas, and/or legendary and you don’t have an enduring story, you have an enduring story for the rest of the game.”

Enduring story is a designation that has no rules meaning other than to act as a marker that other rules and effects can identify. Any number of players may have the enduring story designation at the same time.

After a player gets an enduring story, continuous effects are reapplied before the game checks to see if the game state or preceding events have matched any trigger conditions.
