Question: Why are you assuming they have two when 1 lost last round? Could they have salvaged 12 cards that would have made that terrifying of a Dune Scorp Sanc Stall?
Yes, one lost, but the discard was still 18 cards -- the number of Light cards in their Blessed Dune decks is less than 12 so they could have saved them all. If Time planned their Vault well in the beginning, they would have packed extra Sundials and Dunes because they were on-element choices.
But then again, I don't really expect all too great of a beginning Vault for them, since only three people on Time actually do any of the planning work: Jen-i, SnoWeb, and DevilLoss.
