I was bored, so I threw together a quick ranking of cards using Councilroom stats, multiplying %+ by Win Rate With. It is sort of accurate, but even with the multiplying by %+ a few must-buy power cards are surprisingly low, like ambassador and masquerade. Also, cards that are easily acquired on spare buys, etc. display an inflated ranking. (pawn, cellar)
And then there are anomalies that I can not explain, like crossroads.
$2:
Crossroads: 78.7

$3:
Fishing Village: 92 The highest rated card, probably due to the fact that it's bought like every game, even when worse than silver.
Silver: 86.142
Great Hall: 76.734 ...What?! I guess people buy it a lot.
Shanty Town: 73.108

Swindler: 67.6
Black Market: 66.27 High, but thinking on it, BM does deserve to be higher than it gets on the Qvist rankings.

More to come! If anyone has ideas on how to improve the rating system thingy, please tell me.
The major issues I notice are: Trashing is too low and villages are too high. VP cards are also rather high. Some inaccuracies may be due to newer players, but improvement is still certainly possible.
Villages being high might be okay; as a community we don't rank them highly since they're so abundant, but lots of boards change significantly if all of the villages are removed.
I'll post 4 and part of 5 tomorrow evening probably.
