Roxiee said it well but I'll reiterate. Gastrodon provides a Water immunity which is obviously very valuable for Ground, and is a solid wall in general. Landorus-T is a great bulky set up Pokemon that often runs Gravity which supports the rest of the team, has a great ability in Intimidate which can be used to check many physical threats, and provides a Ground immunity. Nidoking is Ground's best Special attacker with incredible coverage all of which is boosted by its Sheer Force and is useful against many types such as Steel, Fairy, Grass, Flying, Poison and more. Mamoswine is a strong wallbreaker and can hit nearly anything for neutral damage thanks to its Ice, Ground, and Dark (or potentially Fighting) coverage. It's helpful against Flying and Dragon-type teams, the latter which is one of the only types you'd wish you had a Garchomp when facing as it's better at dealing with stuff like Kyurem and Dracovish than Mamoswine is. But nonetheless I hope this explains how all of the Pokemon in the A rank have valuble roles that are helpful in multiple matchups as opposed to Garchomp which isn't necessarily bad to have but is less useful than the rest.Could you explain this one to me? I'm fine with the drop, but I don't really understand it or why Garchomp as a Pokemon isn't as valuable as the ones above.
