Speaking of which, that Sp. Def should always be the main selling point over regular LO Mewtwo. Sure it can't take a physical hit but Ubers is 80% special sweepers and none of the Mewtwos take priority well so it's a moot point.

It's certainly not the best pokemon in the game but it's definitely not as useless as some people think.
