Pokémon X and Pokémon Y

So decided on Pokemon X (however I still love Mewtwo Y way more than Mewtwo X ). My friends told me of a shady game store pretty close that I may have to visit tomorrow for reasons....

If it helps, Mega Mewtwo Y is now the strongest pokemon in the game. Arceus has 720 base stat total, Mega Mewtwo Y has 780. It's a powerhouse.

EDIT: woops, read your post wrong. (it's 2am, i'm sleepy. no idea why i'm still up)

I'm sure someone would be willing to trade you their Mewtwo Y.
