A player cannot recruit a leader that is already on the game
board, in a leader pool, or eliminated from the game.
• If all of the leaders shown on the player’s drawn action
cards have already been recruited, the player may
continue drawing action cards one at a time until he
draws a card that shows a leader that he has not
• A player can choose an action card even if he cannot
recruit any of the leaders on the card. He gains the card
but does not recruit a new leader.
