One of the main things I've noticed about ambassador is that it can actually help your opponent if they're aiming to get 5 or less coins each turn. In this (
http://dominion.isotropic.org/gamelog/201207/14/game-20120714-160553-4f293f41.html) game my opponent opened with amb/silver and I opened with bureaucrat/silver eyeing the duchies, dukes, and silk roads. My deck was able to handle the junk from his ambassadors and jesters rather well because I had a lot of silvers and also the coppers that they gave me were more of a benefit than a problem since I only wanted to get to 4-5 coins. My opponents bureaucrat purchase on turn 10 was probably a mistake but I think he might've been hoping to play something like bazaar/ bureaucrat/jester and hope to get more vps in a long game but my deck was better positioned to score large amounts of points in a long game. He probably should've tried to get a better duchy split than 2-6 because the 6 duchies really boosted my dukes. Any ideas that might've gave ambassador a better chance or any ideas on how I should've improved my play?(I didn't buy ambassador btw, it was passed to me) (Edit: changed name to sound less like an article)
