This is where the meta starts to feel a lot like Rock, Paper, Scissors.
Skorpios is the type of deck that can cheese wins out of a lot of good, competitive decks, but it also has match-ups that are practically unwinnable, like Eater/Siphon Anarch. It's a deck that gets better the less people are prepared for it, so I wouldn't expect it to completely take over the meta any time soon, but you could probably count on at least one person trying to play spoiler with some sort of rig shooter. When it works it spits out easy wins.
I wouldn't call it a total deal breaker if your deck can't handle Skorp. I doubt you'd hit it more than once in Swiss, and everybody drops a game or two from time to time. Hopefully if they make the cut someone with the right tools knocks them out before you face off again.
The thing with the meta right now is that there isn't really a deck that has great match-ups across the board.
