I already have all of my basic and mighty knights on the board. I played the Deserter Politics Progress Card to one of my opponents, and they chose to remove a mighty knight.
It only says in the Almanac,
If he chooses a knight that you do not have available (for example, if he removes a “strong” knight and both of your “strong” knights are already on the board), you may place a basic knight instead.
But I figured since the strong knights have a lower rank than the mighty ones (which is the type of knight my opponent removed), I can place it on the board.
Am I allowed to build the strong knight instead of a basic knight, because it is a lower rank than the knight removed?
Should I have promoted my basic knights first to have at least one on my supply, prior to using the Deserter card?
