All right: My worst:
Trader
Oasis
Highway
Inn
Scheme
Ill Gotten Gains
Crossroads
Noble Brigand
Haggler
Smithy
I'd totally want to do some Haggler + Highway here, but given that I suck so bad at all these cards, perhaps Smithy Big Money is the way to go, possibly shifting to push IGG if the opponent goes that way.
I feel like going Traders + IGG would be strong on this board, as Traders can help block some of the cursing the opponents do, and trashing an IGG for 5 Silvers feels fairly strong. Traders are also really good for Duchy rushing, although I'm sure you can pick up a couple Provinces with a deck full of Silver.
I don't know whether picking up a Haggler is good here though: I feel like Haggler + Highway is a Nombo because there are no buys, and you can't pick up anything extra if you buy from a $0 pile. Highway also doesn't let you pick up anything you couldn't already have picked up from Haggler. I'm also unsure about Smithy Big Money because of the presence of Noble Brigand.
Traders + IGG is also probably weak to Noble Brigand, but probably your deck is so full of silver that losing a couple won't hurt too much compared to the cursing attack.
