But then you should (and I think you really shouldn't) open Embargo-Procession at least. I tried this board a couple of times against bots and I can't help but feel that there is an elaborate Double-Tac with Proc-Proc-HG-Rebuild to be played that gains Estates and Duchies via trashing HGs and rebuilds them in the same turn while gaining back Rebuild and HG. The problem is that you run out of supplies that way, so you also need Villages to gradually be processioned into more Processions and processioned Scavengers give you an extra gain when you double-Tac. Even if this doesn't beat regular Rebuild on average, I think at the very least this would be an approved use of Rebuild, because it's actually fun and not lame.
