No problem.
Like I said, while it is entirely possible that I am getting criminally unlucky, I do think it'd be a huge coincidence that I got none of those moves on the list of moves that can't be called by Metronome (
https://bulbapedia.bulbagarden.net/wiki/Metronome_(move) (that's the page for reference, I mean the boxes that are blank)). Besides, it wouldn't make much sense for Sketch to be callable by Metronome anyways...
