I like your ideas
A thing about the night:
The village blacksmith turns into a wolf whenever there's a full moon; when there's a crescent moon, he turns into a chihuahua
Seems like the night is not always the same...
could be that in the progress of the game, some wheel (or card) for the moon phase is turned, so that cards can have different effects throughout the game. Maybe cards give boons or hexes, depending on this moon phase?? Since there are two different types of cards (Fate and Doom), each one of them could have a good effect and a bad effect through two different moon phases (Half moon, full moon). Through this, timing would get more important and an interesting interplay could happen if one player buys fate cards and the other buys doom cards
About the cards:
tragic hero (Doom): Maybe it is like a normal hero (+2, gain treasure) but it gains a hex, depending on the moon?
cursed village (Doom), blessed village (Fate): gives the second action only in the fitting moon phase
faithful hound, weerwolf, vampire,... (Doom): Strong attacks with hexes at full moon, weak or no effects at half moon
Pixie, Pooka, Monastery,... (Fate): Strong good effects with boons at half moon, weak or no good effects at full moon, maybe defenses against Doom cards
