Just would have won a game with it, but my opponent resigned.
LOAN
BRIDGE
VILLAGE GREEN
Start 4/3, get a Bridge and a Loan. From now on, do not get any more treasure. Buy Village Greens and Bridges alternately while you loan away all the copper.
semi-final turn: Play a loan. It will go through the entire deck, discarding all the village greens for next-turn play.
Final turn: play all the bridges. Profit.
Its a bit too slow, i think it will loose to big money. A secound trasher would help.
I can imagine it could also work with other diggers than loan (Rebuild, Hunting Party) if you have a way to get rid of the coppers.
