Time's up. no more guessing (not that I got any guesses). The answer is: The Haunting of Bly Manor
Manor, Haunted Mansion, Way of the Ghost - self-explanatory
Chapel, Dollhouse/Chest of Expensive Clothes - self-explanatory if you've watched the show
Guardian -Dani the Nanny
Statue - for the statue garden
Groundskeeper - Jamie
Thief/Villain - Peter Quint
Swamp Hag - Viola/ The Lady in the Lake
Majordomo - Mrs. Grose (not quite, but I don't have any fan cards called 'housekeeper')
Here's another themed kingdom if anyone wants to guess what the theme is:
Lackeys, Poet (in the OP), Arsonist (in the OP), Generous Benefactor (RSG), Theatre*, Mill, Secret Society*, Inventor, Scholar, Baker (use shelters, replacing Necropolis with a Ruined Library)
Theatre
$4 - Action
This card has the same types and abilities as the card on the Theatre mat, but gives an additional +1 Action when played.
---
Setup: Put a $2 costing Action that gives +1 Action unconditionally onto the Theatre mat.
by grrgrrgrr (Thanks to those who made
the trello page for the Weekly card design contest or it's be nearly impossible to find any particular card in that thread unless it was a winner or runner up. I liked this one.)
Secret Society
$4 - Action
Shuffle the Secret Society deck and reveal the top 2 cards. Play this as one of the revealed cards. This is that card until it leaves play.
-
Setup: Secret Society deck is made up of ~10 different action cards each costing $5.
by Cookielord. My only mod was making it cost $4 instead of $3.
