>>38054276>Checks and CountersPokemon Immune to Ground: Skarmory, Rotom-W, Zapdos, and Celesteela take very little from most of what Landorus-T can throw at them. The same applies to Gliscor, which eventually wins out versus faster non-Z-Move variants of Landorus-T if it switches in on anything other than Hidden Power Ice.
>Bulky Grass-types: Tangrowth can wall any set that doesn't carry a Z-Move. The same applies to Tapu Bulu, which can both set up on Landorus-T and further hinder its general functionality with Grassy Surge.
>Water-types: Greninja and Manaphy outspeed non-Choice Scarf Landorus-T and force it out with their STAB attacks, with Ash-Greninja threatening Choice Scarf variants with Water Shuriken. If Rotom-W switches in on Earthquake against Choice Scarf or defensive Landorus-T, it can force it out with the threat of Hydro Pump or Will-O-Wisp. Gyarados is immune to Earthquake and can potentially use the opportunity to clean up versus non-Stone Edge variants.
>Ice-type Pokemon and Ice-type Coverage: Kyurem-B, Weavile, and Mamoswine can easily OHKO Landorus-T with their STAB moves, with the latter two beating Choice Scarf Landorus-T with Ice Shard. Ice Punch variants of Mega Medicham and Mega Lopunny can put a lot of pressure onto Landorus-T, as it will often need to use its resistances to pivot through them, and similarly, it's not uncommon for more defensively inclined Pokemon like Clefable and Mew to carry Ice Beam for Landorus-T.
>Strong Special Attackers: Landorus-T struggles to take hits from the likes of Mega Latios, Heatran, Tornadus, and Tapu Lele, since it has mediocre special bulk.
