The problem with Nomad Camp in this specific game is that unless I intend on picking up a Festival, it will collide with the Trading Post. The +Buy that Nomad Camp or Festival would have offered would have been helpful with the Quarry, yes, but I would have been relying on the ability to top-deck both terminals and the Festival every turn. I wouldn't be surprised, though, if opening Nomad Camp/Quarry and going for a Festival and massed Schemes (with the TP, obviously) outperformed my more basic strategy in the long run. It just seems like a very complex strategy requiring lots of cards and thus less likely to set up successfully.
