Adamant Nature
- Swords Dance

- Roost
Swords Dance (raises your attack up to 876, therefore you can break much teams with only technician bullet punch, also if you set 2 swords dance attack will become 1314, and if you set 3 swords dance attack will become 1752, when you will be able even to OHKO volcarona with bullet punch, which is the biggest counter for mega scizor in OU).
Bullet Punch (totally sweeper move for mega scizor, and after one swords dance in OHKO's about EVERY Pokémon which get 2x damage from steel ((or more)), after 2 swords dance any Pokémon which don't resist it, attack it can OHKO scizor's biggest fear, volcarona ((as I said before)) ).
Bug Bite (only now i've seen this, but bug bite get's a technician boost, raising it's power up to 90, making it another great wallbreaker move. even though mega scizor is not that fast, it should be able to hung a move which is not fire type, or even a fire punch coming from an electivire ((i've done this before)) and then kill it. is also a great counter to electric and water types which resist bullet punch).
Roost (heals you, you most likely will not take damage from 50% your health if the targetis not a fire type, and you won't saty on if the taget IS a fire type. since you are not a flying type Pokémon, it is just like recover. I pretty much recommend it for healing if you see you'll die, and using it for be able to hung on some moves ((insane defenses)). then just sweep your opponent with 876-1752 atk STAB technician bullet punch ((swords dance)). have you got it? if no, ok. is just for healing and support :3).
I've been swept for this innumerable times before (and swept the my opponent too :3) and it is HELLISH. seriously, there is almost no way you can kill it.
