In the heat of the most recent SPL, we've experienced a rise in the usage of Heatran, Zeraora, Zapdos, and Tornadus. This increase has created an open niche for a Ground-type like Garchomp that can compress defensive profiles for the four effectively. Landorus is direct competition to this set, although Garchomp sets itself apart with a variety of tools that Landorus does not possess. It handles many other defensive and offensive names of the tier better than Landorus, due to its prized speed, bulk, typing, and wide movepool. Personally, I've used this set for quite some time and it's surprising that it gets very little recognition. While not exactly being a meta staple, it plays an important role on teams that need its support while being highly customizable and unexpected.
The set above is basic SpD Chomp, maximum bulk with leftover investment to outspeed Timid Magnezone and other things creeping at 240. An EV spread of 252 HP / 200 SpD / 56 Spe can be used to account for offensive variants of Heatran. With a Careful nature you outspeed Modest Heatran, and with a Jolly nature you outspeed Timid Heatran. Moves likes Aqua Tail, Dragon Tail, Flamethrower, Fire Blast, and Draco Meteor account for its flexible moveslots, with some variants even opting for a defensive SR 3A variant to fit as much coverage as possible.
