How do you get rid off the move that Smeargle copied with Sketch?

Question

How do you can rid of the move Smeargle copied? Example: My Smeargle copied Metal Claw so how do I make the move go back to Sketch?

Answer 1

You'd have to level it up so it can learn sketch over the move you want to remove, or in the case of HMs, you can use the move deleter.

If your smeargle is at level 100, however, you can find heart scales to give to the move re-learner, who will let smeargle re-learn sketch (not any other move).

Good luck!
