Adamant Nature
- Close Combat

- Facade
Close Combat, Pin Missile, and Rock Blast are all pretty much necessary on Mega Heracross, but the last slot is wide open. With a multitude of options, such as Swords Dance, Substitute, and Bullet Seed, it's almost impossible to guess what Heracross will carry. But regardless of what it carries, burning Heracross tends to stop it dead in its tracks. All of its moves are weaker with a burn, except Facade, which actually gets stronger.
Although unboosted Facade is out damaged by an unburned Close Combat or Pin Missile, once Heracross is burned, Facade becomes its most powerful move, allowing it to retain its usefulness in breaking offensive teams.

252+ Atk Mega Heracross Facade (140 BP) vs. 0 HP / 0 Def Manaphy: 219-258 (64.2 - 75.6%) -- guaranteed 2HKO
-1 252+ Atk burned Mega Heracross Rock Blast (5 hits) vs. 72 HP / 0 Def Landorus-T: 70-85 (20.7 - 25.2%) -- approx. 0% chance to 4HKO

252+ Atk burned Mega Heracross Pin Missile (5 hits) vs. 248 HP / 252+ Def Rotom-W: 105-120 (34.6 - 39.6%) -- approx. 23.6% chance to 3HKO after Leftovers recovery
252+ Atk Mega Heracross Facade (140 BP) vs. 248 HP / 252+ Def Rotom-W: 151-178 (49.8 - 58.7%) -- 74.2% chance to 2HKO after Leftovers recovery
As you can see, with Facade, Heracross still has the muscle to punch holes in teams that rely on things like offensive Lando-T or Rotom-W in defensive cores.
