Destiny Decided is a great card to play when you have more cards on the table than the opponent and you are planning to win in 1-2 turns. You will use your spaceships/missiles to win the game and don't really need to play any more cards in order to win.
It will seriously slow down the opponent in the end game when you normally play perhaps 4 cards per turn.
