The scheme card says to spawn a defeated captain. If there are only two heroes and two captains on the board would I spawn a third? I am reading it to mean I would only use the two captains in a two player game.
I played as the card states. Started with 2 captains in a 2 player. Still had 2 on the board. Since neither was defeated there is no spawn. If a card says "spawn a captain" then I would spawn a 3rd.
Of course if I was to really do as the card says I would spawn a captain that enters play defeated and then he would immediately come off the board.
