>>371720641) LGPE are their own separate metagame where most of the Pokemon have utter shit base stats aside from legendaries, mythicals, and Mega Evolutions. Melmetal is a big metal fish in a small shitty pond. Hell, it is the best Steel-type there, with the other 3 being garbage.
2) Melmetal was never going to be completely terrible in competitive, because it has really good physical bulk, a great defensive typing, and great physical attack. It's most likely RU material if Gen 8 ever comes around.
3) LGPE cut out many of the mechanics that would make it difficult for a Melmetal to thrive, such as most entry hazards, recovery outside of Rest and Eevee shenanigans, and abilities.
