Yes, I have read the FAQ. I am still confused.
It seems to indicate surge etc. triggers any time a card is "revealed" from the deck. But some cards do not use the "revealed" language. For example, Dunlending Attack, stage 2b of the Fords of Isen mission says, "...searches the encounter deck and discard pile for 1 different Dunland enemy and adds it to the staging area."
Nothing about "revealed". So if I choose to add Dunland Prowler to the staging area (while I have 3+ cards in my hand) does Surge activate? My instinct says no, the card was not "revealed", so surge would not trigger.
Of course I said exactly the same thing about cards with Surge during setup, and according to the FAQ, Surge does indeed trigger during setup. So I am not sure how to play.
