Accelgor excels as pretty popular Special Sweeper during single battles. This setup is intended to take down the opponent's team with devastating special attacks. Choice Specs will increase the damage of Accelgor's special moves by 1.5x but will lock you into the first move you pick. With Sticky Hold, Accelgor cannot lose its held item due to another pokemon's ability or attack. This moveset really does work well in Ubers. Accelgor's outstanding speed allows him to outspeed most unboosted opponents, and Choice Specs gives him some firepower, boosting his SAtk up to 492. Choice Specs, plus his great speed allow him to bring punishment as a revenge killer and as a late-game sweeper. As I said previously, his main role is to check things like Darkrai and Mewtwo that could otherwise pose a threat.

Prepare for single battles with Accelgor as a sensational Special Tank. It's primary goal is to absorb special attacks and counter with decent force. Leftovers are always a great recovery option to ensure Accelgor last longer regaining it's life every turn. With Hydration, Accelgor has its status cured at the end of each turn if rain dance is active.
