First shot at GAT

Hello all. Its been awhile since I played any magic. Not much time and Ive been playing other CCG's. Well in any case one of the local shops is going to be trying Vintage tournaments for awhile and I will have time to play... I think. I decided to I wanted to build a GAT deck and I wanted to get some feedback on the list I wrote up.

I don't know what the meta will be so I haven't put a sideboard together for the deck, some ideas for the board would be welcome. I disliked the idea of a fourth color in the deck and opted to leave out the red although I'm not totally committed to leaving it out and may put it back in. Well like I said Id like some feedback on the list so without further ado heres my list.

Creatures:
2 Psychatog
4 Quirion Dryad

Spells:
4 Gush
2 Ponder
1 Berserk
3 Misdirection
1 Mystical Tutor
1 Vampiric Tutor
1 Demonic Tutor
1 Echoing Truth
2 Mana drain
3 Brainstorm
2 Duress
2 Thoughtseize
4 Merchant Scroll
1 Yawgmoth's will
1 Ancestral Recall
1 Timewalk

Mana sources
1 Black Lotus
1 Mox Sapphire
1 Mox Jet
1 Mox Emerald
3 Tropical Island
4 Underground Sea
2 Island
3 Flooded Strand
3 Polluted Delta

So thats the list so far. What do you think?

EDIT:

Please forgive my lack of content I know better I was pressed for time and hadn't yet goldfished the deck yet. Well having had plenty of time to fish the deck (I do little to nothing at work) at work I have a better feeling for what I do and don't like about it.

After last night I'm less then impressed with Pyschatog's performance my preference runs to the dryad but other then Tarmogoyf (Which has gotten outrageous price wise). I'm not sure what to replace the Tog's in the deck with I was almost thinking of just adding another couple more draw spells in the slot or a combo kill like Empty the Warrens although I don't want to add red to the deck. If I drop the togs I can drop the berserk from the deck as well freeing up three slots in the deck so I may just increase the ponder and brainstorm count up to four each. So possible changes to the main may look like this:

-2 Psychatog
-1 Berserk
+2 Ponder
+1 Brainstorm

I think those changes may help the deck with better consistency. The only other gripe I have had with the deck while playing it (I use workstations solo test mode) has been with the Mana Drains. They at times were a help or more often a hindrance at the 2 count but dropping them to 1 seems harsh I might try and replace them with regular Counterspells although that may depend more on the meta in m y area when I have a better chance to see what it will look like.

As for the sideboard I have yet to work on that because I'm unsure as to what my meta will look like so this is kinda of what I'm gonna look at till I have an idea of what he meta is like.

Sideboard:
4 Leyline of the Void
2 Duress
2 Thoughtseize
2 Echoing Truth
3 Oxidize
2 Trygon Predator

I think that may work for the time being untill I have a better idea of what the meta will look like. I thinks thats it for the time being I'm gonna go and see if I can get a game on workstation with it to see how it plays out. Any ideas are welcome.
