When playing teams, the teams may trade cards with each other. This allows them build combos and use their seat position to their advantage. As an example, one teammate might give another a supply card and take a settlers card. Then, once it's their turn, they can lay down a one two punch of supplies then play a settler.
Once a player is successfully Nuked, they are out of the game. This means either last player standing wins, or the first player to 200 settlers.
