Well, the Master would die during his fight with the Doctor. I wouldn't let Evolto kill the Master because I want to balance the Big Bad role between the two, and letting Evolto kill the Master would make Evolto too much of the true Big Bad (though he is).

With the Master's death, two cases happens:

1. The Master was killed in his essential form, and stays dead.

2. The Master regenerated into Missy.

In case 2, Missy started out somewhat villainous, but eventually reformed and became an anti-hero. Leading two two cases for her fate:

1. Evolto kills her.

2. She continues to stay alive, or was wiped out along with half of the multiverse only to be resurrected later, then moved on and began a new, peaceful or adventurous life for herself. Could be an actual new companion of the Doctor.
