Melmetal's primary counters are Ground-types like Groudon and both formes of Landorus. Melmetal's excellent bulk and numerous resistances grants it a lot of freedom when it comes to overcharging, and can easily store charge moves while switching out to search for better targets to unleash them on. Although Melmetal may not exactly win some of these matchups, it can threaten Ho-Oh, Yveltal, Excadrill, Snorlax, and Zarude super effectively, allowing it to function as a check when combined with its spamminess. Melmetal is also no slouch offensively, having slightly higher ATK than Togekiss and Giratina-O, alongside extremely spammy charge moves that have great coverage combined. It primarily functions as an answer to Dialga, Lugia, and Togekiss. Melmetal's Steel-typing and solid bulk allows it to be a stalwart backbone to many teams in the Master League. However, unlike Registeel, Melmetal can hit Pokémon like Charizard and Gyarados for Super Effective damage with Rock Slide. It's a powerful Steel-type, often functioning like Budget Registeel. Melmetal is better in Ultra League than Great League. Other Pokémon can just do Melmetal better in open format. Still, though, the combination of Rock Slide and Superpower gives it solid coverage against relevant meta Pokémon.

However, with the release of more and more powerful Steel-types, it has fallen out of favor. Melmetal held an incredibly strong niche early in PvP.
