Imagine being able to see the future while on the battlefield. When you see the future, you can see every possible outcome and pick and choose which one will take place. When your opponent plans to make a move, you will literally see it coming a mile away and plan a counterattack accordingly. You could come up with strategies that will inflict maximum damage to your opponent while keeping your own losses to a minimum. If you are a military commander with this ability, you will be unbeatable because you would always control the outcome.
