Ok, after checking it, Scizor have mainly steel, flying, bug, fighting and dark moves. Considering bullet punch is a must, we have steel already and have to choose one out of the remaining 4 Steel + Fighting is Super Effective against: Ice, Rock, Fairy, Dark, Normal, Steel(6) and will hit Neutral on all Mono-type pokemon Steel + Bug is Super Effective against: Ice, Rock, Fairy, Grass, Psychic, Dark(6) and is not effective on Fire and Steel Steel + Flying is Super Effective against: Ice, Rock, Fairy, Grass, Fighting, Bug (6) and is not effective on Electric and Steel Steel + Dark is Super Effective against: Ice, Rock, Fairy, Psychic, Ghost(5) and will hit Neutral on all Mono-type pokemon Looking at this we are down to Steel+Fighting or Steel+Dark. The former has breakbreak that can destroy screen but not boosted by technician and the later has pursuit or thief that get technician boost. EDIT: Ok, I have reset my EV to HP and Sp.D and I want to say I am pretty disappointed. I havent try it on many battle but four and I can say so far it that for most of the time I just cant get that +4 Sword Dance and therefore cant kill a single thing. With TalonFlame and Blaziken, all over the place I was forced to switch out. Azumarill which is currently very popular can wall Scizor attack easily even at +4 since steel deal neutral damage, Fighting and bug is not effective and I dont have flying move.
