Nope. Shadow Ball Mewtwo is no longer Mewtwo’s most powerful moveset due to the damage output rework a few months ago, and Giratina’s Shadow Claw/Shadow Ball combo outpaces Mewtwo’s overall Ghost-type damage output by 400 points. I’ll be using Mewtwo as a Psychic-type attacker, but only until I get a better one, as the one I currently has falls below my minimum requirements for level up. (93% with perfect Attack, while the Mewtwo I have is a 91%).
I would have used Bug-types against Azelf, but Fire Blast dissuades their use, and it’s been difficult to predict which moveset Azelf will have based on the Recommended Party. For instance, in this more recent raid I did, it recommended Kyogre and Palkia initially, which normally would be indicative of a Fire-type Charge move, but Azelf ended up having Future Sight instead. Due to the unpredictability, I chose not to use Bug-types against Azelf.
Should Uxie and Mesprit arrive, I’ll be using more Bug-types like Scizor and Pinsir. I would use Yanmega, but Uxie has Thunder and Mespirt has Blizzard on top of Azelf knowin Fire Blast. Sharpedo will likely be rotated out in favor of these Bug-types for Uxie and Mesprit.
