Those move legality posts from earlier reminded me to take a look at the expanded learnset for Metronome for myself now that it's a TM once again with more opportunities to learn or relearn it since Gen 3, and there are some interesting expansion choices that I can get behind, where it seems a lot more lenient to what counts as a finger. The old HOME TM list basically just stuck to the mons that had already had access to it in the past so it's nice to see. Vanilla Metronome battles will have a lot more options to work with now and hopefully gamefreak learns from their mistakes and goes back to the 1v1 style of Metronome battles for their official competitions. Maybe Electabuzz and Magmar can eventually return in DLC to get it back after being snubbed in SWSH as Gen 1 TM learners.
EDIT: On the other hand only Mew naturally learns Metronome by level-up of the mons in this game. I guess they might take Jigglypuff material as a substitute for crafting.
