Simm!Master returning to Doctor Who

[laireshi]

BBC had confirmed it a few days ago, and then on Saturday a new trailer for Series 10 was shown after the first episode, featuring one very important second. It's official - Simm!Master will make an appearance in the newest series! (So will Missy, so - we'll get a Two Masters episode?).

I'm very very excited for this, especially considering the last time we've seen Simm!Master on screen, saving the Doctor.
