^That was my main question too. But when I saw the demo video and noticed that there were no "Mewtwos Special attack rose sharply" like you said, now I'm confident the boost will be applied in the base stats instead of being an in-battle boost. Which is better IMO... As you said, if the boosts were in-battle boosts, they wouldn't be that powerful as they would be affected by certain attacks and abilities (I think of Unaware right away)...
