I ran a GPT-2 text generation model (
https://github.com/minimaxir/gpt-2-simple/) against the list of official cards.to see what happens. Many cards are nonsensical or just cloning the existing ones, but some appear to be interesting. Nothing was edited, so most of the names come from the existing cards. I've just helped a little with formatting.
Bandit Fort
Project
$4
At the start of your turn, +2 Cards, then discard 2 cards.
This is a very nice sifter project idea, underpriced to the level that everyone would buy one on first turns.
Madman
Action
$7
+3 Cards
You may play a Madman from your hand.
This super-Cultist looks quite playable, though way too expensive.
Haunted Woods
Action - Attack
$3
+3 Cards
Each other player draws a card.
It's a very friendly attack similar to Council Room. The opponents still can react on it as it's a real attack
Sauna
Action
$5
+1 Card
+1 Action
You may discard a non-Victory card costing up to $2. If you do, +$1 per unused Action you have (Action, not Action card).
Unexpected Diadem effect for a cantrip. In baseline scenario it would gain $1 for discarding a Copper. I would consider buying it for $2.
Walled Village
Action
$5
+1 Card
+2 Actions
At the start of your next turn, +1 Card.
The machine even correctly named this Village-Caravan hybrid as a Village. It forgot to mark it as Duration, but nobody's perfect.
Dame Anna
Action - Attack
$5
+2 Cards
Each other player discards down to 3 cards in hand.
When you gain this, each other player gains a Gold.
I like the idea of compensation on buy of the Attack card. Probably should cost $3.
Swashbuckling
Action
$2
Do you have a card that you would like to be treated with a degree of skepticism? +1 Villager.
The engine's approach to inventing its own card name was treated with a degree of skepticism

Fortune
Treasure
$5
Worth $2
+1 Buy per empty Supply pile.
When you gain this, gain a Silver.
Wow, a Silver+ that comes with another Silver!
Chariot Race
Action - Reaction
$3
+1 Buy
Trash a card from your hand. If it costs $1 or more, each other player gains a Curse and discards down to 3 cards in hand.
When you discard this from play, you may exchange it for a Chariot.
Setup: Add an extra Card pile costing $3 or $4 to the Supply. Cards from that pile are Chariot cards.
This is an impressive mechanics - an extra pile you card can be turned into.
Butcher
Action
$4
+2 Coffers
When you discard this from play, you may put this onto your deck.
Vanilla coffer gainer which may return to top of the deck. It's situational, but cool.
Diadem
Treasure - Attack
$3
Worth $2
When you play this, each other player receives the next Hex.
With $5 cost, it would be a reasonable variant Idol.
Labyrinth
Landmark
When you gain a 3rd card, take a screenshot.
WAT?
