I have one question..

If someone who has MS take MS from other person, which techniques he will has?

Madara took Izuna's eyes, but both of them have the same techniques, so Madara has still Susano'o, Amaterasu, Tsukuyomi.

Sasuke took Itachi's eyes, but it is the same as between Madara and Izuna.

But what will happen if, for example, Itachi takes Shisui's or Obito's MS?
He will have still his own techniques or only their techniques or his own + their?
