Intact decks (total cards 86):
Almost certainly(safe for vaultdiscards 43 cards):
Death rush+frogs (17 cards)
Bonewalldials+SoSac+Miracle (26cards)
Likely (had not lost since they were last played at least 3 rounds ago):
Water duo (NT, Chrysaora) (19 cards, arsenic might have been discarded, vault discards possible)
Total so far: 62 cards, 24 remaining
![Aether :aether](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/aether18x18.png)
duo is probably gone, unless they kept only fractals
![Air :air](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/air18x18.png)
duo could be salvaged from entropy (~16 cards)
![Fire :fire](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/fire18x18.png)
duo possible (salvage deflags and phoenix)
Mono should always be a possibility (would strain the other decks though)
This is assuming they can manage 50% in-element w/o transmuting.
