Two questions:
1`. Can a card used to pay the resource cost for Ancestral Knowledge be picked up and shuffled back into the deck by Ancestral Knowledge?
2. Chaos in the Prison (from the Wrecking Crew): "When Revealed: Choose to either discard an upgrade you control or place 1 threat on the active villain's side scheme for each upgrade you control."
I am not sure if the "for each upgrade you control" part applies to both options or just the latter option? That is, if I have 5 upgrades, should I choose for each upgrade if I would discard it or place 1 threat (e.g. I can choose to discard two upgrades and place 3 threats), or should I choose to either discard one upgrade or place 5 threat?
