I'm interested to see you guys think I would go for a gardens rush here. First of all, I don't think a true rush is even very close to being possible here. But let's say you mean what I would call a gardens slog - get a couple support cards, go straight for the green, and slam into copper every chance you get. So here, a couple horse traders and then slam gardens. Well, I am not sure how strong that is in general, but I don't think all that strong. You really need to get duchies to make that work, and then, do you get the duchies first, or the gardens first, because duchies are harder to get later, but gardens are more important for your strategy. And then, you are going to stall out, so you probably should be building up more, but then you have enough money to go for provinces, and pretty soon you're just playing a weird version of big money, where you always buy copper, get up to province a time or two, maybe don't buy them anyway, and then really slam the green. It can work, but generally only on a weak board.
I guess this is what timchen said, but in many more words.
Anyway, I didn't even consider it here - you HAVE to go for that apothecary/wishing well engine, it's just too strong...
So, in any case, annotations attached, video here:
Let me know what you think!
