Apparently Smash said: "The hosts are testing which types Sylveon fits… what could it be?! The hosts tested to see if Sylveon was Fighting – she failed. Next they tested to see if she was strong against ice – she was! She was strong against Ice, so they tested if she was Steel by attacking her with poison type – She wasn’t resistant to it, in fact, it was super-effective against her!"
This isn't any known type right now, so... New?
