You could probably make a decent aggro-control deck that is similar...but forget about the combo part and insane will turns.
It'd probably go with low cost draw spells like night's whisper, cantrips like opt and alot of disruption similar to smemmens last list (8 Duress, 4 fow)
I'm not sure if psychatog would be the best creature for the deck without gush to feed it, it you're running intuAK it's probably good enough...but intuAK is rather mana-intensive.
Card draw you could try:
Dark confidant
Night's whisper
Opt
Sleight of hand
Without gush in the deck, confidant probably won't hurt too much. This draw engine is very black though, so you'd still need alot of blue cards to feed fow and possibly misD.
A new GAT deck should probably run 5 Moxen, 1 lotus, 1 mana crypt and maybe even lotus petal...Since you don't need lands the way you did before, and night's whisper and confidant both require

, and to me they seem to be the best option.
One thing to remember is that your bad match-ups will be alot worse now, since you can't lucksack out of them as often.
Creatures:
Quirion dryad - Might grow a little slowly now, but might be worth running.
Psychatog - Really needs an engine to feed it, Gush was really good at this, so is intuAK.
Tarmogoyf - Probably better for the deck now, since it's easier to get it huge right away.
Dark confidant - Wasn't played before, but you're gonna need some card draw, and this might also help out the hungry psychatog.
I'd try something along these lines:
Creatures: (10)
4 Tarmogoyf
4 Dark confidant
2 Psychatog
Disruption: (12)
4 FoW
3 Thoughtseize
3 Duress
2 MisD
Draw: (14)
4 Night's whisper
2 Opt/Sleight of hand
1 Ancestral recall
1 Brainstorm
1 Ponder
1 Merchant scroll
1 Gush
1 Demonic tutor
1 Mystical tutor
1 Vampiric tutor
Broken: (2)
1 Yawgmoth's will
1 Time walk
Utility: (2)
2 Cunning wish
Mana: (21)
5 Mox
1 Lotus
1 Petal
4 Underground sea
3 Tropical island
5 Fetch
2 Island
That's 61 cards...But it was only meant as a guideline as i have not tested it. Regrowth might be worth running.
I upped wishes to 2 since it's harder to tutor chain for them, and drawing that 1 naturaly is tougher.
The mana base might need some work aswell..And i'm not sure if petal is worth running.
