Nominating Landorus-T as a
Check
Landorus-Therian (M) @ Rocky Helmet
Ability: Intimidate
EVs: 252 HP / 112 Def / 144 Spe
Impish Nature
- Earthquake
- Knock Off/Toxic
- U-turn
- Stealth Rock
Defensive Landorus-T can safely come in on CB Tyranitar's moves barring Stone Edge (91.8% chance to 2HKO after Stealth Rock) following intimidating it, threatens Rocky Helmet chip barring Stone Edge, and following such chip, can OHKO it with SR up after Earthquake (50% chance to OHKO after Stealth Rock), and safely OHKO with attack investment if chosen. With further defensive investment, it
approaches counter territory, as it only needs 16 EVs invested into it's speed to outspeed Adamant CB Tyranitar. Given this, with max defensive investment (240 def, 16 speed), Tyranitar only has a 1.2% chance to 2HKO after Stealth Rock. Given that Tyranitar would be locked into a move, Landorus can also pivot out and switch to a teammate that resists the move the opposing Tyranitar chooses to gain momentum on it, making Landorus-T a
hard check (not quite a counter). Oh and did I also mention it doesn't take sandstorm damage?
