So, pretty easy question, right. You could answer to the follow up question asking what you think is missing from the set. For example, I just noticed there is no typical terminal 3 card draw. (Wharf is kind of, but not completely.)
Just for funzies, I am not Donald's secret second account to collect information.
I am a pretty conservative kind of a guy. At least, for this expansion it seems. Only Embargo, Pearl Diver and Navigator, I guess, have to go for me. If I had to push it, maybe Sea Hag for a slightly more interesting curser, treasure map because of it's swingyness and maybe Smugglers for the same reason. But generally, I think Seaside is pretty good. Embargo, I feel, can go because Swamphag is a better version of it. I have used embargo too many times on scout or pearl diver kind of piles, just to be able to use the terminal +$2 and never have to bother with the curses either way. Pearl Diver is just awful (and Haven is a better pearl diver anyway). Navigator, although, I guess, useful in slogs or something, has never really appealed to me. Cost relative to benefit is just insane. Maybe if it wasn't terminal.
Oh yeah, and pirate ship. Forgot about that. Ugh. Pirate ship.
