cr:5.4.7a

A while-static ability is functional when its while-condition is met and when its source is public, when its source is private if the while-condition explicitly specifies it, or when its source is private and the while-condition specifies it functions in that private zone. Otherwise, a while-static ability is not functional.

Example: Heave is a while-static ability that means “While this is in your hand, . . . ,” where the while condition specifies the source being in a zone that is private by default. This means that Heave is functional when its source is private in the player’s hand.

Example: Blood Debt is a while-static ability that means “While this is in your banished zone, . . . ,” where the while-condition specifies the source being in a zone that is public by default. This means that Blood Debt is not functional when its source is private in the player’s banished zone.
