I must say, with hazards up and a good Gliscor lure, Jolly SD Scizor is a very powerful sweeping threat. Jolly lets you beat all the stupid subCharge Magnezone running around and lets you get the jump on most bulky waters with a +2 LO Bug Bite.
Another highly underrated offensive setup sweeper is Nasty Plot Jynx. It has the unique ability to not only switch in on almost all rain stall, but it has the ability to 2hko or 1hko every rain stall member, with the only exception being spdef. Jirachi which is 3hko'ed by +2 Ice Beam. Tentacruel, Politoed, and Chansey are massacred by Psyshock, Sassy Ferrothorn is 2hko'ed and can only break your sub with Gyro Ball, and Perish Song doesn't really prevent you from coming in on Toed and throwing up another sub. SubNP overall is a fairly safe switch-in vs. most bulky waters, particularly things like Suicune and Vaporeon, but it really shines vs. rain stall as you can come in for free on the primary spiker/spinner Tentacruel and proceed to set up safely. Even rain offense has a tough time with it, as politoed's strongest hit is Focus Miss or hidden power which doesn't do great damage and allows you to sub spam for a miss, and you outspeed specs sets and can scout their attack, and having a sub up lets you demolish the frail sweepers like Tornadus and Toxicroak.
