Personally, I don't like the journey token very much. That is why I would rate ranger lower than most people did so far because I consider it highly situational and only good with village support to play 2 of them consistently.
Miser seems like a card that you wantto make work, but don't most of the time. I agree that it should be on ther lower ranks.
Also, I don't think caravan guard is as bad if you can somehow gain them. Looks like an awesome upgrade/remake target in engines aswell as Haggler target if there are no other cheap engine components.
I'm not sure how strong artificier will be, though.
The card I'm most excited about is Haunted Woods. I think the attack will range from very bad (estates are trashed, only dead actions cards left) to very good in the greening phase. I'm most interested how silkroad/garden strategies work against a haunted woods engine, because it lets you have a dead turn almost every seconds turn.
