Accuracy Corrector is quite a strong card, although often overlooked. The ability to ensure your dice remain a constant threat throughout the game is fantastic. Also it is worth nothing the card reads 'may' not 'must' cancel dice in order to add the hit results. This means when combined with the Darth Vader crew card for example and Gunner you can pull off some nasty effects triggered effects twice in a round.
This card is a great fit for the TIE Advanced purely because of its native 2-die attack. This allows for the ship then to act in a purely defensive role taking the evade action each round.
