The strategy is to buy many Silvers and other $3 cards in the beginning and then remake them all at once into Silk roads. Your opponent could have no clue what you are up to just when you gain 3 Silk Roads in a turn (buy Remaking 2 Silvers plus buying one) and maybe 2 in the next and there are only 3 left for him before he might react.
After the Silk Roads are empty, you just have to keep buying Silver, Estates and when you can Duchies (try to empty Silkroads, Duchies, Estates).
I don't know how far this works for gardens, because green is not all you need for them to function and Remake doesn't increase the number of cards in your deck.
I just had a game with also Ambassador and Crossroads in it where we both were doing the normal Ambassador thing, I was able to buy an early Gold, and just tried Remake and got 2 consecutive turns with 3 Silk Roads. He only bought 1 so I got 7 Silk Roads, while he bought 7 Provinces but I also got most of the Duchies, so I won 70sth to 40sth (game is not on Councilroom yet so I'll update it later)
