       text: If any objects break any restrictions of card abilities or the game rules (such as the Runner's memory limit) or are installed or hosted in an illegal location, an appropriate set of those objects are trashed. A set is appropriate for this purpose if trashing the objects in the set would leave all remaining installed or hosted objects in legal locations and if no object can be removed from the set while maintaining that property. If there are multiple distinct appropriate sets, and one player controls all the objects in each of those sets, that player chooses which set to trash. If the sets contain objects controlled by both players, the active player chooses which set is trashed.
