Yeah I see no huge advantage on 5/2.
What about Hermit/CY (on 5/2), and grabbing nothing but Labs, Peddlers, and Madmen (maybe 1 or 2 Silvers if need be), and ignoring Hag altogether? If all your opponent is doing is playing Hag every third turn or so, shouldn't Hermit be able to take care of that? And more importantly, if that's all they're doing, then they're probably building other things pretty slowly. And then once the Curses are empty or near empty, pull the Madman-Masterpiece megaturn, and green from there. I just don't see a straight Hag-Silver-Lab thing outpacing that, unless they get a big lead on Provinces, which I don't think I see.
