A while-static ability is functional when its while-condition is met.[5.4.7]
Example: Yinti Yanti has the text “While this is defending and you control an aura, this gets +1{d},” which is a while-static ability that is functional when it is a non-permanent defending card because it has a while-condition that is met when the card is defending.
