Salvager, I don't know if it's 'way too high', but it seems a bit high here. But in response to
But, I really cannot see how this card is better than Spice Merchant or Moneylender for single card trashing.
If you're looking at it to trash down, you're doing it wrong. That's not the primary purpose of the card. Somehow people have also missed one of the purposes of the card, which is to give +buy. Well, you may say that remodel increases the value of your deck more, and this CAN be true, but being able to have the flexibility to use that money ANYWHERE and split it up amongst different cards, pooled along with the other money you're producing, is what
usually makes it better than remodel. Enough better to justify this big a gap? I'd say probably not, but better.
Well that and that 5>3+4 a lot of the time in dominion, and nothing>2 most of the time.
As for other things: Death Cart, I haven't played with it much, but it's got to be way high here, but you know that's somewhat on me - I rated it even a good bit higher than this (what was I thinking?). I think Wandering Minstrel is a bit low, yeah that's old, but what I really don't understand is how throne room is the best village here. I mean really? It's decent, but there's a lot of times you actually want regular old village over it, which is definitely not something you can say of the others. Finally, conspirator. Well, it has more upside than the other cards here, but so often it's a bit dicey. I mean, it is so good if activated, and so bad otherwise. You want to have it in a big engine, but the more conspirators you have, the less likely that engine fires. It's good, but I think I'd have it a bit lower.
