I agree that it's not token druid due to no Violet Teacher, but I also think this deck is stronger without Violet teacher. I think the arguses are fine, maybe you could take one out. I agree that Haunted Creeper would be a good addition to this deck as a 2-drop.
I also like Piloted sky golem over Cairne. It's much more threatening on board, and creates a lot more lethal threat than Cairne does. Cairne vs. Sky Golem is close, and I don't think either is bad, but I like Sky Golem a bit better here.
I think I'd definitely want 2 shades instead of one, if you're cutting cards. Maybe I'd cut 1x Argus + something else for 2 Haunted creepers. Not sure what the something else would be, though.
I also would consider cutting Dr. Boom. It's your only BGH target in a meta where every deck is running BGH. I think another legendary would be better in its place (Loatheb? Cenarius? Maybe even take it out for Haunted Creeper depending on what your bad matchups are. I guess Cenarius doesn't fit with this deck's philosophy, I feel that Loatheb would be a good fit stalling for a turn before combo though.) I think decks either want multiple BGH targets so they can't hit everything, or zero BGH targets so that your opponent can't get great value. Right now, I would imagine it's getting hit by BGH a ton.
