Drampa is really late. Don't know what your starter is but you have two weakness to flying and no resist maybe using a Rock or Electrik type to resist and kill would be a good idea :
-Lycanroc
-Minior
-Togedemaru
-Oricorio-PomPom (it's the earliest one so that's cool)
And if you have no problem using Alolan-form from Gen 1 :
-Alolan-Raichu
-Alolan-Golem
