This set looks like a great engine set, but is missing any +Buy. However it is possible to still gain 20+ points on one turn. It took me a while of looking at this to figure it out.
Stonemason, Doctor, Fishing Village, Menagerie, Coppersmith, Feodum, Ironmonger, Cache, Catacombs, Harvest
Stonemason can be used as a +Buy to trash Catacombs into 3 Feodum and Feodum into 5 Silverhttp://dom.retrobox.eu/?/20130719/log.50775a4a0cf28ed55d9d6fd3.1374285229110.txt
