Copper is "fine" in duke-duchy games if your getting it for free with an extra buy. It is not really as good as silver though since with silvers you can buy duchies and dukes even in hands with green in them. So I would not buy talisman. I also don't see the point of farming village. Yes, it will "skip over green" but that's only relevant if your trying to sift through your green to get some power card you want to play. Here, your only real "power card" is silver, so you could just buy that instead. Well I guess Mandarin is sort of a power card, but I don't think its strong enough to justify buying farming village over silver.
Also, I think you could have used 1 or 2 more mandarins.
I also don't really see the point of savager since you want your coppers so while you can use it for estates and boarder villages, there are allot less of those so allot of times you might draw it and find you have no use for it. I guess I could see getting 1 to trash estates and give you extra copers, but 2, in my mind, is overkill.
