Player A casts a Quarantine Field with 4 targets (targets don't really matter), Player B has an active Lux Cannon (5 counters and untapped). Do the targets get exiled or does the exiling effect fail to happen?
Quarantine Field exiles with a duration. If that duration ends before the effect begins, the effect never begins. So while the Field's trigger will resolve, it will do nothing to the targets. They are not exiled forever nor are they exiled and returned.
Note, that older cards like Oblivion Ring are different in that they return the exiled cards with a trigger. They do not exile with a duration. In case of such a card, the target is exiled and can't return if the exiling permanent leaves the battlefield before the target is exiled.
