Ghost is a very passive type, considering a lot of it is focused around status moves paired with defensive boosts (CM, AA, toxic, wisp, etc.)
Thought id give a try at a glass cannon for ghost.
I gave banette tough claws because of it's design, it literally has its claws sticking out of its hands
Pros:
Dark typing to give it a weakness only to fairy moves, as well as give STAB to knock off and sucker punch
And it naturally gets gunk shot, so it atleast has a move to check fairy with.
Prankster was an ability i feel m.banette didnt fit well with, so I gave it tough claws to add power to its contact moves
Ghost now has an answer for hoopa, clefable, and STAB sucker punch is just awesome to have.
Cons:
It is still so frail, and has no recovery
All of it's status movepool is useless pretty much, since it's pretty slow and prankster was what benefitted it
