But doesn’t your point just mean that even at Adamant it isn’t a 1HKO, therefore outspeeding MMY with Jolly won’t KO it, and therefore you have 1 less reason to go Jolly?
(1)
Jolly:
252 Atk Choice Band Sand Force Aerodactyl-Mega Diamond Storm vs. 252 HP / 252 Def Mewtwo-Mega-Y in Sand: 322-381 (77.4 - 91.5%) --
31.3% chance to OHKO after Stealth Rock and sandstorm damage
Why use a Ground Typing in your Calcs and why double Diamond Storm’s base power? Just use the actual calc:

Anyways here is the % of winning with Adamant:
252+ Atk Choice Band Sand Force Aerodactyl-Mega Diamond Storm vs. 252 HP / 252 Def Mewtwo-Mega-Y in Sand: 355-418 (85.3 - 100.4%) --
81.3% chance to OHKO after Stealth Rock and sandstorm damage
Also for Imposterproof I like Ferrothorn:
252 Atk Ferrothorn Gyro Ball (150 BP) vs.
+1 252 HP / 252 Def Aerodactyl-Mega: 230-272 (32.6 - 38.6%) -- 99.3% chance to 3HKO
(2)
*i gave it Chansey’s Base HP, and +1 to account for
Eviolite. Also it can Prankster Spore, and can sit there and stall.
Whereas:
252+ Atk Sand Force Aerodactyl-Mega Precipice Blades vs. 252 HP / 252+ Def Ferrothorn in Sand: 114-135 (32.3 - 38.3%) --
1.8% chance to 3HKO after Leftovers recovery
*Remember, Imposter doesn’t copy Choice Band...
Mind you, that’s with a neutral Defense nature, and not Fur Coat. Plus, since it would be on my Sandstorm team, it would carry
Shore Up to go with Prankster Spore...
They make a great pairing since Ferro can switch into Rock, Electric, Water, Ice
(3), Steel... Spore, Toxic, literally all of its weaknesses.
Aero can switch into (Special) Fire moves.
Head Smash is a last resort, sorta like how people use Final Gambit to take down walls, or Destiny Bond to take down sweepers.
Head Smash only does a % of the damage dealt. And as you can see in the Giratina Calc (reposted here for convenience), it will actually be able to do it multiple times unlike a successful Final Gambit or Destiny Bond.
252+ Atk Choice Band Sand Force Aerodactyl-Mega Head Smash vs. 252 HP / 252 Def Giratina in Sand: 375-442 (74.4 - 87.6%) -- 6.3% chance to OHKO after Stealth Rock and sandstorm damage
(4)
*Factor in 6.25% Sandstream Damage and Stealth Rock (and it’s really 93.15% minimum Damage- Leftovers would heal after Sandstorm).
(51.5 - 60.7% recoil damage)
I disagree with diancie’s Versatility, as the only moveslots for a Sand Force Set would be 1 with Sunsteel Strike, Diamond Storm, and Precipice Blades, and Play Rough (to differentiate it from Aero).
Only going mixed, would Diancie-Mega have versatility, but again it would need 3 Rock, Steel, and Ground moves on a Sand Force Set, and only 1 moveslot for Fairy. So unless it goes Weather Ball, Earth Power, Sunsteel Strike and Moon Blast, I don’t see it going mixed, at least not with the Sand Force Ability.
It can’t afford to be slower than its counters
(5), like Magic Guard Diancie, so yes it must be Timid. But Mewtwo (without Sheer Force Bolt Strike) as
Chessking345 mentioned, won’t be able to 1HKO always Aero, regardless of Speed, and Aero can’t for sure Guarantee 1HKO MMY. The answer is to not have Aero fight MMY, because it will take a hit before it KOs MMY and you would rather just send in a Counter to MMY than take a heavy hit before KOing first if Jolly.
Only Head Smash KOs MMY; and I would rather use that to KO a wall.
TLDR- Sand Force Choice Band Mega-Aero is the Choice Specs Mega Launcher Ash-Greninja of Sand Teams. Both have 399 Speed, weather boosted moves, and just enough power to justify using over their bulkier counterparts.

I think discovering it’s Sand Force Power will make it an essential part of any Sand team that needs to justify not using another weather.
