I wonder when there is another factor in equation, RNG. In some turn based strategy games, even if you know what kind of attacks the boss can unleash there still a chance, even if is 1%, to cause a miss hit.
One example is Xcom Enemy within where there was a soldier with 95% chance to hit an enemy and he simply missed and vice e versa (10 % chance to hit and he targeted the enemy).
One of the Hearthstone challenges also follows this pattern, the boss plays the same cards in the same order, but your cards only provides random effects that even knowing his strategy, RNG can simply help or defeat you.
