Oath out of the sideboard loses to the same hate as flash so boarding it in is stupid and useless. The sliver package is a lot more effective since it beats extirpate.

I believe that you are forgeting about vendillion clique . It's a duress affect on legs !

In this deck enlightened tutor seems like it is too slow and doesn't get enough stuff that would be effective right away.
Trinket mage gets all the same stuff except counterbalance and he is a 2 butt.

That is the worst downgrade for bouncer ever. Even trinket mage is starting to sound good.

This is what I would consider doing.

Switch out magma jets for 2 fire/ice.
Switch out null rod for 3 of any combination of REB and pyroblast.
Switch out brainstorm for 3 duress.

This gives 3 extra slots for some mox.
I have a few other comments, but I'm not one who should be molding decks.
It would be awsome though if you could give us some feedback our tourny reports on Izzet Guildmage

Just out of curiosity Engine no. 9, where do live in the US where  fish is so bad.Other posters ignore this.

If you are sooooooo afraid of  fish in the format just run 4 FTfrickingK board.
Some of my original comments on that deck that I was going to write were so harsh that my ears started to bleed and my eyes fell out of their sockets.
I hope none of you  fish players took that personally.

You could also think of cutpurse as an ancestrall recall every time he hits because it's plus 2 card advantage.

The problem with trinket mage is you're not just just taking out spots for mage ,but also for artifacts that the deck doesn't normally play.First let's think of the decks it is played in.There's bomberman and that random counterbalance deck.The reason bomberman plays it is because it gets them their kill condition,lotus.They need the mage because it is part of a combo.Second of all,the counterbalance deck plays it to get top ;also part of a combo.I can't count number of times e-truth won me a game.Also you have only 4 solid targets to get(EE ,crypt ,lotus chalice)and even lotus isn't that great and t-crypt is even more conditional than e-truth.Also ninjaing back a a trinket mage is cool ,but with the given toolbox it's nothing special.If you have any troubles with your mana that you can't get for cutpurse it's time for somebody to do a little rerouting on the mana base.

the only reason cutpurse is viable is when you play full moxen which I do so I can always play him turn two
I can see why you don't run him because you only run on color mox
his disrupt effect is great though in my opinion

First of all, grim lavamancer just does less than bouncer and drops the blue count  for FOW.
Bouncer is actually weak in the format currently which I agree on ,but there's the chance of not having him
that one match where you need him most and lose because of it.
I also uped the count on duress to four because it had proved itself multiple times against
combo and there wasn't much I could see myself running over itsince the loss of disruption.
The reason for so many creatures is because there are games I lose because I am just unable to put them on
a clock. The cutpurse has been a HUGE help as well as drawing the cards off vamp/mystical.
Having the tutors is great because it allows you to not rely on topdecking.
The thing I can see myself doing is adding a gorilla shaman to 4 since I always love drawing
that and blowing their mana base.
Hopefully that covers every thing which I doubt I did.

sorry about not giving enough imformation
the deck's strong match ups are (Gifts ,Combo ,fish mirror, Slaver ,and stacks if you are a good enough player)
the deck's weak matchup can be stacks if you are not prepared and against oath it is weak and loses to
the random rogue decks
I have placed 3 out of 4 times at type ones with this ,but the time I didn't top eight I won the 32 man side event
at Becker's last tourny
I have playtested a lot also with the deck and it seems to have the best matchups of any of the fish decks I have
played
The deck no longer plays remand or daze unlike the other cards in the deck they just weren't great.
With remand you always had to two mana open and daze is only good early game.
With the edition of cutpurse your hand will never run out.
Also you don't have to worry about pitching creatures to FOW because it plays so many.

This is the list I have playing with for a while now and has proven to be one of th best builds in my opinion.
Here's the list.

creatures
3 gorilla shaman
3 waterfront bouncer
4 dark confidant
3 dimir cutpurse
3 ninja of deep hours

spells and disruption
1 ancestral recall
1 time walk
1 mystical tutor
1 fire/ice
1 echoing truth
1 vampiric tutor
2 REB
1 pyroblast
4 FOW
4 duress
3 chalice

mana
7 mox mana
5 waste effects
6 fetches
3 volcanic
3 U-sea

I didn't post the sideboard because it is obviously meta dependant. I would really enjoy suggestions on what your thoughts
are on the deck and it's use of tutors

Just in case anybody was wondering, the side event had about 32 or 31 people and was single elimination
the last 4 decks were wizard fish, URBana fish, combo with confidant, and oath. Ash took it in the end against
(Sully),that was probably spelled wrong, 2-0 Sully was playing the combo and I was playing URBana
