What third slot should I use with MSalamence and Mimikyu for

>>32801773
Something that resists Ice and Fairy and can handle Ghost and Steel. Scizor (potentially AV) could be a good option here. A Fire type with bulk like Incineroar or Heatran or Arcanine could also work very well but you'd have to be careful of Water type Pokemon with Ice coverage, so a Water type that doesn't feel too threatened by Fairies or Ghosts would be great too.

Swampert,Quagsire,Gastrodon should do the job.
