Your team doesn't have sufficient ways to deal against Conkeldurr, i think. How often do you are using pursuit in it? Maybe changing for a acrobatics would be nice.

252+ Atk Choice Band Technician Scizor Acrobatics (55 BP) vs. 120 HP / 0 Def Conkeldurr: 308-364 (80.8 - 95.5%) -- 12.5% chance to OHKO after Stealth Rock
252+ Atk burned Conkeldurr Mach Punch vs. 248 HP / 0 Def Scizor: 38-45 (11 - 13.1%) -- possible 8HKO
