Battle Of Gods Spoiler
I have no idea what you guys are talking about, Goku did not go Mystic SSJ, and his SSJ isn't stronger than SSJ 2 or 3. What happened in the movie was that he became a SSJ God and fought Bills near equally as he stated he (Goku) was using about 80% and Bills 70%, then soon after he couldn't sustain the form anylonger and reverted to his base. Then after a little five second scruff he went SSJ using the leftover power from SSJ God making almost as strong as the latter, but then was forced into space where he went SSJ God again to barely withstand a GIANT ki ball from Bills.

Forgot to add that the leftover SSJ God does not last forever, for if it did, the first SSJ God as mentioned in the movie would not have been defeated by the evil Saiyans (that's right you capitalize races or species), and would instead would have been able to continue fighting them. What that means in this since is that Goku's SSJ being almost as strong as SSJ God will not last too far after the movie, unless he goes SSJ God again of course (and Vegeta probably wouldn't love to help).
