Oh, I've got a great submission. Here was the full Kingdom: Apothecary, Bishop, Cache, Cellar, Crossroads, Festival, Menagerie, Potion, Tactician, Tunnel, and Vineyard
And here's what I wrote about it:

I wish I had recorded this game; it was definitely the most fun. Tactician, Festival, Bishop, Tunnel, Crossroads, and Cellar were the key Cards. Obviously, there's a lot you can do with that. Mass gaining of Gold with Tunnel/Cellar + mass draw with Crossroads + trashing of Gold for points = the plan. He is smart enough to head down mostly the same route; unfortunately for him, I think he's just a few too many steps behind. He smartly picks up a second Bishop before I do, but the big deciding factor is that I have two Tacticians before he does, and also I am the first to recognize the power Crossroads will have here (we each have a bajillion Tunnels). I have a shockingly bad turn where my 10 card Tactician hand has all my Tunnels but no Crossroads or Cellars, and that worries me a little. Luckily, I rebound just fine, having one turn where I gain like 7 Gold or something. I safely buy the penultimate Province, and although his next turn is really good, there just isn't enough left for him.
Now that I look back at it, it is a fairly complex set. You know, a strategy that incorporates Apothecary/Vineyard isn't so difficult to imagine. Vineyard has plenty of desirable Actions, and Apothecary has Cache. Or you could just use Apothecary as a jumping off point, and keep the Potion for late-game Vineyard. Of course the main route is probably most appealing, but I think there's plenty of finesse involved in deciding how much Bishoping to do, whether to actually get so many Festivals, when to grab the Tunnels and the Tacticians, etc. I think I played it quite well but not perfectly.
