Better Than One

You can give your new teammate Contraptions you control. You can also give them face down cards from your Contraption deck so they can form their own Contraption deck.

You can choose any player not currently in your game. This includes people who used to be in your game but left it.

Your new teammate must be someone not already in your game, although it can be someone who was once in your game but left.

Your new teammate must agree to play with you, although they don’t necessarily need to know how to play.
