Keep/Change/Delete

[CatExe]

Keep, but I'd give it to more Pokemon. I think it makes sense on Muk, Goodra and maybe Garbodor
Stall

 

[Ghost Diplocaulus]

Delete. It has its uses, but doesn't seem to offer enough advantages to warrant staying. Plus, the only Pokemon that gets it has a significantly better option.

Covet

 

[Handium]

Change, right now it’s thief but unable to do super effective dmg and not being affected by kings rock; maybe make it that it lowers a stat instead of doing dmg?

Mist

 

[CatExe]

Change it to remove any negative stat changes on the user as well
Hustle

 

[Camille]

Keep, I guess.
