Seaside, the 2nd expansion for Dominion. It has 26 new Kingdom cards. Its main theme is your next turn; there are cards that do something this turn and next, cards that set up your next turn, and other ways to step outside of a normal turn.

All that is asked is a tall ship and a star to steer her by. And someone who knows how to steer ships following the stars. You finally got some of those rivers you’d wanted, and they went to the sea. These are dangerous, pirate-infested waters, and you cautiously send rat-infested ships through them, to establish lucrative trade at far-off merchant-infested ports. First, you will take some islands, as a foothold. The natives seem friendly enough, crying their peace cries, and giving you spears and poison darts before you are even close enough to greet them properly. When you finally reach those ports you will conquer them, and from there you will seek more rivers. Some day, all the rivers will be yours.
