I can now say that I have bought Vagrant over Silver!
http://dom.retrobox.eu/?/20130622/log.50ec3d53e4b0429cfe0934be.1371919356522.txtI open 5/2 so I go for Mystic/Vagrant with the idea being that when Vagrants fail, Mystics can draw cards. I probably should have picked up a Remake earlier, and I think a Haggler might have also helped, but I still did reasonably well thanks to my 8 Mystics. And, in the early game I preferred Vagrant to Silver.
