Landorus is one of the strongest offensive Pokemon in the metagame with its powerful Sheer Force- and Life Orb-boosted attacks, which threaten much of the tier for super effective damage, including many metagame staples such as Archaludon, Incineroar, and Raging Bolt. It excels at forcing the opponent into defensive positions, creating opportunities to play aggressively with Landorus and its teammates.

Earth Power annihilates targets weak to it and puts massive dents in most neutral targets. Sludge Bomb allows Landorus to hit Grass- and Flying-types such as Rillaboom, Ogerpon-W, and Tornadus, which resist or are immune to its Ground-type moves. Tera Poison elevates Sludge Bomb to a STAB move, which secures the OHKO on Assault Vest Rillaboom, bulky Ogerpon-W, and Alolan Ninetales as long as Aurora Veil is not active.

Sandsear Storm gives Landorus the option of a strong spread move, making it even more difficult to play around and preventing foes with Follow Me or Rage Powder from redirecting its attacks. This move is especially potent when used in the rain, as it becomes a 100% accurate spread move, allowing Landorus to reliably apply offensive pressure to both targets simultaneously.

Alternatively, Substitute gives Landorus the ability to safely fire off strong Earth Powers and Sludge Bombs while attracting attention to itself, which can supply its teammates with opportunities to set up or attack on their own. Substitute guarantees that Landorus will survive at least one attack while behind it, which it appreciates given its mediocre bulk that ordinarily leaves it vulnerable to getting OHKOed by super effective attacks or getting KOed by priority moves when weakened. Landorus's offensive pressure forces the opponent to switch and use Protect a lot, creating many opportunities for it to set up a Substitute. This is especially true when it is paired with Pokemon that can apply Fake Out pressure such as Rillaboom and Incineroar.

While Tera Poison increases Landorus's offensive capabilities, a more defensive route can also be taken with Tera Steel, which turns its glaring 4x Ice weakness into a resistance, allowing it to flip the script on foes that would normally force it out such as Chien-Pao, Kyurem, and Alolan Ninetales. Additionally, Steel is a generally useful defensive typing with many miscellaneous resistances, including ones to common attacks such as Rillaboom's Grassy Glide and Tornadus's Bleakwind Storm, among others.

Landorus appreciates teammates that can set up Tailwind such as Tornadus and Whimsicott, as it is naturally outsped and threatened with super effective damage by common Pokemon such as Ogerpon-W, Chien-Pao, and Alolan Ninetales. Effective speed control and positioning can allow Landorus to gain the advantage on these foes and others, making Pokemon that supply redirection support useful teammates as well, including Indeedee-F, Ogerpon-W, and Sinistcha. Teammates that struggle either offensively or defensively against Fire- and Steel-types, such as Gholdengo, Kingambit, and Kyurem, appreciate Landorus's ability to neutralize those threats.
