Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Old but still gold, here we have an offensive Landorus-T with Earthquake + Stone Edge. This set uses Gravity to use our main attacks to their maximum because with this move we neuter Levitate users and make Flying-type pokemons grounded, so Earthquake has few safe switch-ins. Also, Gravity makes Stone Edge a lot more reliable.
U-turn is here to keep the momentum.
The EVs spread is a standard offensive one, whereas Lum Berry is to prevent annoying status (mainly burn), and Tera Water because Water is a good defensive typing.
Hazards support is appreciated, especially Spikes/Toxic Spikes since Gravity allows them to hit more targets than usual.
role compression mon with rocks, pivoting, speed control, and 2 immunities all in one slot! tera ground is useful for boosting the power of earthquake, but tera flying w tera blast can be used for flying stab even if it is tera reliant.
