It is said that, those who control two mangekyou sharingan produce the third one, susanoo, and i haven't seen Sasuke using any other MS apart from amaterasu.
He already used all 3 on the anime and manga. He used tsukuyomi on a random cloud ninja before killer bee and killer bee when he went into his chakra cloak form. He used amterasu on killer bee and raikage. He used susanoo on raikage and the kages so far. What more do you need? Re watch the anime or re read the manga.
