Hi all. I've noticed my technician mega mewtwo x set being used recently so I figured I'd post it.
Entrée (Mewtwo-Mega-X) @ Lum Berry //Lum berries seem to work the best, since if you get spored, you wake up and then use shift gear, which allows you to outspeed anything that's unboosted (e.g. deoxys-speed)
Ability: Technician
Shiny: Yes
EVs: 252 HP / 252 Atk / 252 Def / 252 SAtk / 252 SDef / 252 Spd
Adamant Nature
- Storm Throw
- Gear Grind
- Bonemerang //or Dual Chop, you can switch around those three moves
- Shift Gear
The main problems exist in the accuracy of gear grind and bonemerang, which can be annoying at times, so you could forgo shift gear for coil, although you can 1hko most things after boosting once with shift gear, thus avoiding any possible damage. It's really up to you.
Here's a potential alternate set.
Entrée (Mewtwo-Mega-X) @ Lum Berry
Ability: Technician
Shiny: Yes
EVs: 252 HP / 252 Atk / 252 Def / 252 SAtk / 252 SDef / 252 Spd
Jolly Nature
- Storm Throw
- Gear Grind //You could also run dark void with coil (and replace one of the two-hit moves with it), which works well after the accuracy boost, but you'd lose coverage
- Bonemerang //or Dual Chop
- Coil
One of the best things in this set is STAB storm throw, because with technician, crits, and stab you get a roughly 200 base power move that doesn't check for defense boosts (which has been handy many times).
An important thing to note is that you want a counter to this on your team. I ran a gale wings charizard y set which resisted all of the moves my mewtwo had, but technician mewtwo hits hard, so you might want something bulkier.
