You've seen all the themes; here then are just some cards I want to show off.
Taskmaster is a tricky village. It can be there for you turn after turn, if you keep working on those $5's.
King's Cache is the King's Court for Treasures that you never knew you needed.
First Mate is a tricky draw-to-X card. It can be a big village and draw a bunch of cards, or not do much at all.
Shaman is the inverse Cathedral. This game, the junk will keep coming; you will have to figure out something there.
Journey is an exotic extra turn, where you won't get to use the cards from this turn on that turn. And it messes with stuff like Swamp Shacks.
Cursed gets Loots into the Traits; some card this game will come with two more cards. Yes now you will have to be clearer as to what you mean when you refer to a Cursed Village. You can also have a Cursed Cursed Village or a Cursed Blessed Village.
And Patient, which waited its turn, makes a card easy to play, if you're willing to wait for it.
That's 20 cards, 15 landscapes, and 15 Loots, from this monstrous expansion. Which we currently expect on Monday online, and around Monday in physical form.
