I decided to see how well my list matches with the best openings, pairing with a few typical non-terminals. I've sorted base on the order on the council room page and colored base on my rankings, with redder being higher and bluer being lower.
with silver:
masquerade
ambassador
chapel
sea hag
young witch
bishop
swindler
remake
salvager
steward
island
monument
moneylender
militia
smithy
envoy
cutpurse
navigator
This is reasonably close to my rankings, with bishop a bit higher and militia/cutpurse a bit lower.
with fishing village:
masquerade
ambassador
young witch
sea hag
chapel
remake
steward
bishop
salvager
monument
envoy
swindler
militia
moneylender
smithy
cutpurse
island
baron
navigator
remodel
Now steward jumps up, as with fishing village an steward, you already on the fast track to a good-looking engine going. Monument also jumps up due to the nice monument/fishing village combo strat. And bishop stays high.
with lookout:
sea hag
young witch
ambassador
monument
swindler
militia
moneylender
bishop
salvager
masquerade
remake
island
steward
cutpurse
bridge
Now masquerade drops because masq/lookout is worse than masq/silver. Moneylender jumps because while it's weak at trashing alone, combining with lookout makes for good trashing. I'm surprised steward doesn't jump as well. The "estate trashers" also take a hit because lookout already knocks out estates, though I'd still think remake would be good.
with loan:
sea hag
young witch
bishop
masquerade
salvager
ambassador
steward
remake
militia
monument
island
envoy
remodel
cutpurse
chapel
Bishop is again surprisingly high. And moneylender is gone for obvious reasons -- loan does the same thing but better, which would turn moneylender useless too fast. Steward jumps here as I would have expected it too with lookout -- while its a bit slow trashing on its own, it's great when paired with a non-terminal trasher.
with chapel:
monument
sea hag
militia
young witch
bishop
treasure map
bridge
swindler
salvager
cutpurse
conpirator
ambassador
moneylender
smithy
steward
masquerade
baron
remake
horse traders
black market
island
envoy
navigator
The VP chip cards are high here because they combo well with chapel, and the elite openers are lower because they don't. Militia is high because it counters chapel well, plus gets more repeated plays in the slimmer deck. Remake is surprisingly low.
with warehouse:
sea hag
swindler
ambassador
young witch
remake
moneylender
monument
militia
treasure map
cutpurse
baron
chapel
bishop
Swindler is high because you can repeatedly attack. Militia and cutpurse don't share this benefit because warehouse is weak when attacked by hand-size reduction, making attack/silver a better opening. Steward is mysteriously MIA, and salvager is gone because it doesn't play well with the smaller hand given by warehouse.
with tournament:
ambassador
chapel
masquerade
steward
swindler
fortune teller
trade route
chancellor
Here we're limited to $3 cards so there is not much to say. Steward is better because you want to trash into a slim enough deck to increase your chance of drawing province with a tournament.
I'd say that the general picture I get out of this is that I may have the +$2 attacks too high. Based on this data, it may be appropriate (as WW noted) to swap the attack and VP tiers. Other than that (and the note I've made about steward), I'm pretty happy with the list.
