If it were me, I'd open Scheme/Sea Hag. I'd keep picking up Schemes with $3 hands, and alternate Remodels and Heralds, depending on how the game goes. By turn 10, the curses will probably be close to gone if your opponent goes for the mirror, and if you have enough Schemes you should be able to get in a Remodel almost every turn. Then you've got some flexibility in the endgame; you can either try to remodel your deck into BM, or you can go for a Bridge and pile out Estates if your opponent has also gone after Schemes.
Edit: if you get 5/2, I think you go Mint-Embargo. You've got about an 80% chance of hitting a $3 hand T3, then grab a Silver. Mint your silver, then grab Remodel, Schemes, and Heralds. With Necro you should be able to draw your whole deck by like T5, at which point you have a bunch of different options; you can remodel Silver into Bandit Camp/Estates into Bridges and go Engine. Or you can go BM and Mint your Gold, then Remodel Provinces into Provinces in order to speed up the end.
