Candlestick Maker will be a power card.
Stonemason is only good because of the overpay, but will be better than Candlestick Maker because of it.
Doctor will be almost but not quite on par with Steward.
Masterpiece won't be worth it unless the kingdom is very weak, or Feodum is out.
Advisor will be a mid-power $4 card. Having +1 Action will make the choice more difficult than for Envoy, but searching through 3 cards counterbalances that.
Herald is fantastic and will primarily be bought for $5 to repeatedly topdeck key cards (like Cursers.)
Plaza will be decent, and is around Worker's Village power level.
Taxman will look like a trap, then turn out to be very strong in niche conditions, and will be strong in those conditions only when many copies are bought. Like Noble Brigand.
Baker is solid, not a power $5 but certainly above average.
Butcher will be played primarily for +2 Coin tokens, the trashing will be used sparingly.
Journeyman-Big Money will be a top-tier BM enabler (almost on par with Courtyard and Jack, below Wharf)
Merchant Guild is only going to be good when it's possible to get multiple copies out, otherwise it's too slow and weak.
Soothsayer will be better than Witch, because unlike all the other Cursers it gets better once the Curses are out.
