I have this preview from my father, who had it from his father, who had it from his father. Who won it in a cat's cradle contest, if you must know.
Seven cards in Nocturne come with an Heirloom. Let's see one.
That yellow band means, everyone replaces a starting Copper with the listed card. In a game with Shepherd, you have 3 Estates, 6 Coppers, and a Pasture. In a game with Shepherd, Pooka, and Cemetery (they're coming in a second), you start with 3 Estates, 4 Coppers, a Pasture, a Cursed Gold, and a Haunted Mirror. See how it works?
Shepherd can draw lots of cards if you have a bunch of Victory cards. Pasture meanwhile is a Victory card that rewards you for holding onto those Estates, or getting more of them.
Pooka lets you trade a Treasure you didn't want for +4 Cards, that seems completely innocent. It can't trash Cursed Gold but everyone has their limits. And as it happens you have some Cursed Gold. It's a Treasure worth $3 but you get Cursed each time you use it. Do you buy that great card turn one and get a Curse with it? I can't make that decision for you.
Cemetery trashes cards when you gain it, that's pretty sweet. I will just tell you now, it is great to gain it with a Workshop or something. It means everyone has a Haunted Mirror, which gives you a little sub-game to play to get a Ghost. And there's Ghost, another Spirit. It comes out at Night, finds an Action, and does it twice on your next turn.
