They had great brutal powers to attack each other, but in the end the convenience came from the gods because they had the power bestowed from heaven. 'You don't stand a chance' situation makes it even worse, the gods have ace up their sleeves. They made a comeback when we felt they had fallen.

It will obviously be difficult to win if you only depend on luck.
