Alright, I made the changes, all except for Stallbreaker, which I'd like to voice my few last thoughts on.
For one thing, I agree that it's job as a stallbreaker is not only not as useful now since stall isn't as crazy as it was a long time ago but also the other sets do express anti-stall notions as well- having Taunt and AcroGem on AcroGemScor or Taunt/Toxic on Substitute are more than enough to wittle through most stall nowadays.
I also had a few problems with the fact that it's supposed to be a kindasorta offensive tank too. I think this role is slightly outclassed by Lando-T now, who is infinitely stronger and bulkier. Plain SDScor's offensive prowess is definitely not comparable to the force AcroGem has, nor is it's defensive ability enough to rival with Sub/Defensive. As alexwolf said, a great thing about Scor was it's ability to wall Terrak, and with split evs like those, it's not going to be able to.
I'm going to spend some time now to move SD into OO. If anyone has any objections, now would be the time to speak up
