(How long until people who haven't played DA aren't allowed to toss their wild speculation into every thread? It's not because I don't WANT to play it...
)
Anyway, here are things I want to try:
Rats/Vineyard rush
Transmute/Feodum (edit: Actually, Transmute might go well with a lot of these Actions that want to be trashed, especially Cultists, Ruins, and Rats, for quick Duchy rushes? I suppose it'll still be the weakest TfB around, but damn it, I'm excited to get to use it.)
Herbalist/Counterfeit actually might not be a bad opener either, for fast and efficient Copper trashing.
