The main use for this card in the modern card pool is for tech against quests with locations that get have brutally high threat, like Forest Battleground. By moving it to the active spot when it appears, you never have to quest against it.
The other use case is with Path of Need. Quest with everyone, then when a location appears you swap it out, complete the new active location, then travel again to the one with Path of Need to have its effects active during the combat phase.
