1} Finale step and missions:
-Does the game favour heroes?
ie. both sauron and hero token would finnish in the same turn but heroes move first.
"At the end of the Story step, if a story marker has reached the
Finale space (at end of the Story Track), the game Finale begins." (p. 33)
So Finale kicks in only at the end of the Story step, meaning all tokens are moved first, then checked (Shadow Falls also applies to the above quote).
-When are missions used to achieve total victory?
Same situation as above, does sauron count as neither dominant, or heroes dominant.
What if neither are dominant?
First you check for dominance. If Sauron has it, reveal Sauron's Mission, if complete -> Sauron wins. If Heroes have dominance, revealtheir Mission, if complete -> Heroes win. If there is a tie for dominance, both reveal, if one has complete, other doesn't, complete Mission wins. If you have a tie and neither (or both) have completed their Mission -> final combat. If you don't have dominance, you can never win by Mission.
2) Random shuffle cards in peril, encounter and corruption cards
These are a bit random.. Are they just means to reshuffle your deck if you have good cards in discard or general method of reshuffling the decks
since these lack any priority and there's no mention of reshuffling decks.. These cards just seem a bit too ackward..
In encounter you can't decide to use it, the corruption version is just weak.
Decks are reshuffled when you exhaust them as well. IIRC, the Peril reshuffler gives the Hero a Corruption card and then shuffles the deck. It's still better than nothing, especially if you draw 2 location-specific Peril (and the Hero isn't at either one). Also, if you know a Hero is going to or through Moria, but the Balrog is already in the discard, might pick the reshuffler to hopefully draw Balrog when the time comes. For the Corruption deck, "Wretched" is my absolute favourite (as Sauron) card. Immediate end to the Hero turn is huge (especially if you get it even before their Rest step). Others aren't that great, lose 2 Favor one can hurt at a critical time. With no reshuffler, you might not see the same card twice, giving the Heroes the ability to card-count (okay, so Wretched is gone, I can risk a corruption since my turn won't end), with the reshuffler, I've seen Wretched drawn 3 times in a game.
