I've been meaning to post a response to thank you for documenting this combo.
I read it a couple months ago when I frankly was getting a little bored with Dominion both online and IRL. This combo interested me so I tried it out a couple times. Even though I slipped up first time I tried it against a bot, it still performed amazingly, and only took a couple extra turns to finish the game. Mostly though, this combo just had me grinning from ear to ear. It is such an elegant and powerful combination. I don't think I have played a combo which is so much fun. It restored my interest in the game, and gave me hope there were other combos and strategies I was still unaware of which could bring back the fun factor.
Thanks!!!
