Imagine a Pokemon had Me First and the Pokemon its versing had a move that was super-effective against itself and the Pokemon used Me First, would it be super-effective or not?
So, if it's Clefable versus Duskclops.
Clefable used Me First, while Duskclops tried to use Shadow Ball?
Yes, Clefable would use the exact attack Shadow Ball, and it would be super-effective, and damage would be calculated based on Clefable's stats.
