Concerning late game Sea Hags (after Curses have gone): Do you keep playing them and why?
I always think: Once my opponent has started buying Provinces, it's better to increase his shuffling rate so he draws his green more often and gets to $8 less often. On the other hand, I'm cycling the cards he used to buy that Province into his draw deck faster. Sure, it's only 1 card, but does anyone have any strategy with late game Sea Hags?
Let's assume we can't trash them, they'll remain in our hands until game end.
