Then the behaviour you get is expected one. There is no bug or issue there.On page 12��in section 3.2 (Starting to draw a card)��it tells you to implement a drawOnSparta: method. After that you should get the same as on Figure 3-1.
Since you didn't implement it, you obviously get nothing. It is like to only��buy a garage and then being surprised that there is no car inside ;)
