(Sorry for my bad english).
Great Hall - Mill is the improved version.
Great Hall is a good card. Yes Mills does better, but the simplicity of Great Hall is interresting.
The card only provides VP but does not encumber the deck. Buying this card is a risk (losing a turn of the game), but it can make the difference at the end. There is a lot of association with a victory card costing 4.
=> Engines deck with more buy, remodel, Workshop (!!!), Ironmonger/Courtier (few cards with this mechanism...), Quarry, Swindler, end of game purchase, etc ...
I kept Mills and Great Hall. It is regularly bought.
Coppersmith could be better. I want a card to replace it!
Spy is slow... As Scrying Pool...
The cards that I find unbalanced:
- Stash: is a good cards. But better if it cost 4? It enters into competition with cards costing 5, and it is not bought.
- Talisman: why "non-victory card"? she would have been better and funny without that.
- Navigator: why not like "Scouting Party"?
- Bureaucrat: it slowed down the deck.
- Loan: only good in engine deck. Why "discard" the good cards?
- Harvest: why discard?
- Rebuild: + 1 action seems too much.
- Explorer: It enters in competition with the cards costing 5, and it is not bought.
- Transmute, rats, possession ...
But it's amazing as all other cards are well balanced!
Many players do not like Lookout, but this is one of my favorite cards! It's fun to play because there is a risk !
