Pokemon X and Pokemon Y

I seriously think it's poison now.
 
Give me your educated guess
 
There was a whole post on reddit about sylveon being based on some poisonous plant, which, when I looked at it, seemed to resemble sylveon quite well.

I'm also bordering on the fact that it could be dragon.
 
The colour scheme seems somewhat correct, and that would explain the "wing" underneath sylveon in that picture, but I still think poison.
