Let's say I've somehow managed to get two or more Exquisite Archangels out onto the battlefield:
(Possibly more. I apologise for making you see this.)
Something causes me to lose. Let's say it's just regular creature damage, and my life will reset just fine with no shenanigans.
What happens? Do all Archangels get exiled at once, or do I exile just one and have one more chance left for each extra Archangel beyond that one?
