Collectible Card Game Headquarters

Describe the Bug:
I have no idea if this is a game limitation but Exquisite Archangel does not exile itself and reset life total on game loss,

Which card behaved improperly?
Exquisite Archangel

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
version 5-2020 10bda4ca0, duel

It's functioning, but not waiting until all damage is dealt. Fixed in ca7d8f937 ("AER further bugfix", 2020-05-22) to only trigger if there are no more damage cards targeting owner.

Edit: In the save game, player was dealt 15 damage, enough to kill them, triggering Exquisite Archangel and resetting life total. But there was an additional 21 damage waiting to be dealt, of course killing them again.
