Minor nitpick: the statistical term is "outliers," not "outliners." Good work nonetheless.
Oh, thanks for the hint. I seem to have mixed it up. I'll change that.
I've gotta say, these community card rankings turned out really great, it worked much better than I thought it would.
I'd bet that Qvist's decision to weight by isotropic rank is really helping to keep the numbers in line. (That and the readers here are generally pretty good at Dominion to begin with.)
I was concerned too, especially in the beginning with few entries, where the order was very strange. With better players sending in their lists it seemed clear to me to make a weighted average. In the end, I can say it didn't change much, a card change here and there. It was more important that many experienced players had sent in their lists, so thanks for all your lists again.
So, the biggest talking points seem to be Scheme, Tunnel, Steward and Swindler.
Scheme: I agree with dondon151, making it a cheap attack is great. And it is a good defense agains Young Witch. It is a nice addition to all decks, it's not outstanding, but deserves its high rank.
Tunnel: Many seem to forget the 2 VP for $3. And that you can generate Golds too is great. Especially if you'd buy the Tunnel enablers (like Embassy or Young Witch) either way.
Steward: It is a very good card, but I was a little surprised it got #4 too. I expected to rank #7 or #6, but it seems that the half Chapel that is still good afterwards is very powerful and liked, even for the top players.
Swindler: It's swingy, but can be devastating. I recently got crushed by Swindler, although I had 5/2 with opening Mountebank.
I'm sorry that the last list update happened already a few days ago, but I will post the first $4 cards in a few hours.
