You're right, Unfezant isn't in there. Neither is Deino, Zweilous, Larvesta, Volcarona, Smipour, Simisage, Simisear, Vullaby, or Rufflet, I don't think. Meloetta, Genesect, Keldeo etc. I know for a fact aren't in there either.
Source: Serebii's List. I think I missed a couple or added some that are in there, but that list is huge anyway, so sorry if I missed any, I don't even own the game.
