I agree that Rogue should be much lower. Yeah it gets you $2, so it's not the worst thing to have, but how often do you really want it? Rarely. If you want to destroy their deck, you need to play it a lot, but then every other time you play it, you're picking up whatever you trashed, so you need to play it twice as much. And then what if the stuff you're trashing just gets in the way of your engine? Seems too hard to use to any great effect. Graverobber I think is better (and reasonably ranked), since even though having it in a random deck is not useful, there's a decent amount of situations where you can make it pretty useful. Throning it with a $5 action in hand is just " discard a $5 action, gain a Province".
It's hard to be too picky with this list, since I think we're getting into the section where most people (including me) semi-randomly ranked the cards. There's probably not a lot separating the top of this list from the top of the next set, but with that said, I have Inn near the top of the next list, not on this one. Just being a village is really useful, so it gets a decent amount of points for that, and even though as an action it nearly didn't get printed for being too weak for $5, once you throw in the on-gain effect, I think it becomes really good, a great way to set up mega-turns.
Since I don't have much to say about the cards that have shown up so far, I want to bring up a card that hasn't: Merchant Ship. When Council Room came back up, it wouldn't load my Popular Buys page since I had too many games, so I started an alt account (Psi Disruptor) to get stats. In 22 games with Merchant Ship, I never bought/gained one, and neither did any of my opponents! Now 22 is a pretty small sample size, and I don't really think it should never be bought, but it was just kind of striking to see. The only other cards I never bought were Thief and Scout. This seems a bit weird since Merchant Ship is "good". It gives a good amount of money. But the problem is that it's really pretty vanilla. It's like Mystic. There's nothing wrong with it, but nothing good about it. This turn it's just a terminal Silver, next turn it's a successful Mystic, and it has problems missing shuffles. I'm usually happy to it with a spare action in a money deck, but if it weren't there, I don't think I'd ever really miss it. I think it's a bottom 20 kind of card.
