scizor is not an especially good baton pass recipient. BP recipients are generally distinguished by resistance to priority, solid stats and abusable movepool/ability. in addition you want them to be useful even when they don't have any boosts passed to them (unless you're running full BP, or they have good boosting options of their own). scizor is okay but it's got issues (slow, and squishy on the special side, relatively unremarkable movepool besides bullet punch and uturn - the latter being unviable on a BP receiver). it's honestly not going to be a quality BP recipient the way jirachi is
anyway if you want to use scizor as a receiver on a quick passing team there are two basic mindsets. either
1) i only intend to use this pokemon if i already have a pass in which case 4 attacks 252 attack / 252 speed whatever nature you want is probably the best way to go. 4 attacks life orb scizor is not especially distinguishing right now and that spread is totally crap for an unboosted scizor (fast scizor is generally not very good in OU - there's a reason CB scizor is 252 hp / 252 atk), but with a pass it'll be pretty good. the movepool you should use is probably something like bug bite / bullet punch / brick break (don't wanna run superpower). fourth slot could be roost, quick attack, night slash, even iron head... whatever you want. you don't have anything super effective against fire types anyway.
2) i intend to use this pokemon for a variety of things but i want it to be able to receive a pass effectively. truth be told this is going to be rather hard to pull off. one of the main reasons scizor is even good in OU is for u-turn and you can't use uturn on a smashpass receiver. sets that run bug bite generally are swords dancers so you could steal either the bulky SD/roost+2 set and spread or the offensive sd+3 LO scizor. both of them can swords dance independently but can still use a smashpass. refer to the analysis for more on those respective sets
