Macbeth

If Macbeth is played while Duncan is on the
field, Duncan is instantly killed. Before
each attack Macbeth makes, roll a die. If the
die lands on a one, Macbeth attacks a friendly
creature instead. If there is no friendly
creatures on the field, the attack is wasted.
Stars, hide your fires!
Let not lght see my black and deep desires;
(I. iv. 50-51)
