Pilots are often reassigned at the last minute for a variety of tactical reasons. Darth Vader ordered DS-61-2 and DS-61-3 to accompany him to the Battle of Yavin.
Use 1 Force to target a starfighter having one or more permanent pilots. Draw destiny. If destiny > 2, deploy on starfighter to remove all permanent pilots (otherwise, Effect is lost). May add one pilot for each permanent pilot removed. (Immune to Alter.)
