Whether I should get a smuggler is an interesting issue. For me, the following things are the factors:
(1) smuggler is only better when you can smuggle BV. Given Garden is expected to be embargoed I don't expect I will be able to smuggle Garden. Otherwise it is "usually" the same as the talisman. Of course, when the smuggler hit with the opponent's province it is pretty bad. (And the talisman is bad when it is drawn with a BV buying hand... which happened more often than I expected...)
(2) However, when it collides with trader, with talisman you can either get one more card by trading itself, getting 4 silvers instead of 3, or you can buy an embargoed card to gain one more silver via trader.
(3) Maybe the most important factor, I was expecting BV to be embargoed. I was planning just to bite the curses.
