[Overview]
~ Possibly worth mentioning that Landorus now shares this unique speed tier with Thundurus-T
[Choice Scarf]
~ you can elaborate that Rotom-W's a good partner, because it's a great answer to many of Landorus's switch-ins (like Skarmory, Forretress, and Gliscor). It can also switch into Water- and Ice-type moves.
~ you can elaborate that Scizor / Tornadus-T are also answers to Grass-types / Latias that may undermine Landorus and Rotom-W's Volt-Turn.
~ although Scarf Landorus's main role is being a revenge killer, mention that it also doubles up as a late-game Sweeper, since it has enough killing power through Sand Force boosts.
[Gravity]
~ Don't forget to mention Gliscor, Landorus-T, and physically defensive Hippowdon as targets for HP Ice, too.
~ Warn readers to make there teams Gravity-proof, since the move effects both sides; they basically should not solely rely on levitators / Flying-types to sponge EQs - they should pack a Grass-type of their own.
~ Specify that Gravity may provide an extra turn to set up Swords Dance / Rock Polish / Substitute, as conventional switch-ins to Landorus are forced out.
[Special]
~ You can compare it to Nidoking - although Nidoking has more versatile moves, Landorus overcomes this shortcoming with raw power (base 115 SpA vs Nidoking's 85). To illustrate, Landorus easily 2HKOs specially defensive TTar.
Focus Blast against a physically defensive Blissey: 43-51%
Focus Blast against a calm 4 HP / 252+ SDef Blissey: 36-42%
Focus Blast against a physically defensive Chansey: 36-43%
~ Calm Mind is worth an AC mention. It provides Landorus the ability to overcome special walls, like Chansey / Blissey. Not necessary for offensive teams, but will certainly come in handy against more defensive teams.
~ Elaborate how Gravity is cool to let Landorus hit levitating / Flying-types with Earth Power and to make Focus Blast super accurate.
~ Mention that these set-up options other than Gravity hinders Landorus's coverage, however.
~ Just like any offensive mon, this Landorus would enjoy entry hazards to seal the kill on more bulky mons. This is especially crucial since this Landorus has no means to boost its offense other than Calm Mind.
~ Latias / Latios easily walls Special Landorus, so a Pokemon that can handle these threats are desired, such as Jirachi, Scizor, or Tyranitar.
~ Gengar can also come in Earth Power / Focus Blast and rip away at Landorus. Same checks to Latias / Latios can be applied to Genger.
~ Pokemon that can take care of defensive Water-types would also be a good partner for this Landorus, such as Celebi and Latias.
[Swords Dance]
~ Unlike the other physical sets, this set can muscle through physical walls, thanks to the attack boost from Swords Dance
~ Unlike the Gravity set, it lures and softens up physical walls like Skarmory, Latias, and Celebi.
~ Other physical sweepers that can take advantage of weakened physical walls, such as Haxorus, Scizor, Lucario, Breloom, and Terrakion are ideal partners.
~ Mention of Magnezone is probably not necessary
~ Superpower is an option to hit Bronzong and Air Balloon Heatran
[Checks & Counters]
~ Gengar is a pretty decent offensive check to Landorus, taking pittance from U-turn and nothing from Earthquake
~ Physically defensive Latias can shrug off Landorus's unstabbed U-turns and set Reflect
~ Specify Breloom as ones with Poison Heal and a defensive spread
~ Include Ice Shard and Scizor's Bullet Punch for revenge killers
