I am making a scizor sweeper. Hes gonna have ATT/DEF evs. this is what im thinking so far, since im going to dragon dance - baton pass to my scizor.
X scissor (has stab)
U-Turn (for switching to my wall if things get bad)
Swords dance (In case dragon dance baton pass fails)
I havent decided a fourth, maybe giga impact for suicides? idk
What do you mean by Dragon Dance - baton pass? As in you're baton passing Dragon Dance boosts to Scizor? If that's the case, then Dragon Dance isn't a passable move since nothing learns both it and Baton Pass.
In any case, defense EVs are not necessary. Standard spread for SD Scizor is 32 HP / 252 Attack / 220 Speed.
