I caught my mewtwo yesterday and I saw its IVs on instacheck and I didn't believe that it had that stats normally .Is that normal in X and Y or I am the super lucky ?and please tell me how to EV it and what moves will be good for it . Thank You.
You are very lucky you got the 4 IV Mewtwo tailored to Mewtwo's strongest stats. This doesn't normally happen. As for EV Training it, since you have the SpAtk IV, train it 252 SpAtk, 252 Spd, 4 HP to make it become a special sweeper.
