I like it! +1

Fatestitcher is an alnative to Aphetto Alchemist that happens to be a wizard... with unearth too! so if you're aiming to combo you can get him from the grave

Curse of the Swine is one of my favorite EDH mono-blue removal cards, being incredibly flexible.

Dream Halls is a psudo-Omniscience that costs a hell of a lot less to play.

Pemmin's Aura is a pretty cool card allowing you to untap wizards and stuff, also good for comboing with an untap creature and Gilded Lotus

Merchant Scroll is a great card if you need it.

Arcanis the Omnipotent maybe?

Similar to Pemmin's Aura is Freed from the Real which is not quite as good, but if all else fails could be used on someone else's creature...

I just realized your land count is 39... Does this work for you? I usually run quite a few less than this and some things like Armillary Sphere and Expedition Map to make up for it... (I run between 34 and 37 in almost all of my decks)

thanks for the advices.
Merchant Scroll and Fatestitcher are great, i'll try to put my hands on them.
i though about Pemmin's Aura and Freed from the Real , but i'm not sure about them.
Dream Halls sounds awesome, but it seems a little risky that it also affect your opponents.
i don't really like Armillary Sphere , but expedition map sound good.
i love Arcanis the Omnipotent , but i'm not sure if it'll work on this deck because i don't have Lightning Greaves nor Swiftfoot Boots

Well, the great part about Arcanis the Omnipotent is that he's got a built-in return-to-hand ablility. And even if you do lose him, he's a very small loss in the end (just a bunch of mana). But to each their own. (he also plays nicely with Mind Over Matter in that you can draw as many cards as you want)

the thought behind the enchantments is that they turn any wizard into a "U: draw a card" creature with your general on the field. And if they have a tap ability then all the better! (like Elite Arcanist )

Dream Halls really the only reason I toss that suggestion is that in blue you can usually win the turn you play it by exiling cards for drawing more cards until you have a combo or something.
