But SCP, from what I've seen in the article, isn't even that smart. He's just a crazy pscyho bastard that kills. He doesn't seem to have any allies. I'm not convinced he's even eligible for this, but whatever, I guess that just means he loses in the first round.
"As a direct result of this, a new task force has been set up, directly for handling and support of SCP-076-2, Mobile Task Force Omega-7 (Aka "Pandora's Box"). SCP-076-2 has only allowed personnel to create and join this squad if they met its personal standards, and could beat it, or come close to it, in anything the applicant chooses.
So far, there are only twenty (20) members of the squad, each having to beat SCP-076-2 in a different activity, as it picks up skills very easily. Mainly, SCP-076-2 has been bested in actions that it would have little to no experience in, and the list of things it has been beaten in has included board games, video games, card games and sharp shooting."
and later:
"Intelligence tests have been wildly inconclusive when applied to SCP-076-2, and no accurate result has yet been obtained. This may be due to the alien thought processes of the subject. SCP-076-2 has however, shown that it has great knowledge of human anatomy (although in a highly violent context), military tactics of open warfare, metallurgy, and, strangely enough, the care of livestock."
Picking up skills at a mind-numbing rate would come in handy in this kind of contest especially considering that Jim Raynor, Einstein and the Stranger from Myst are competitors, though I will concede that his concept of honor in battle and his preferred tactics would probably hamper him. (Though the same could be said for Creed or Sherlock Holmes)
