This is my Niv-Mizzet, the Firemind deck. It's proved pretty solid so far but I am always looking for new ideas, tweaks and tricks any input would be awesome.
mirror sheen (out of the few spells out there that target players, people will decide to not target you...there are better cards to take advantage of this in R/U-redirect, counters, twincast, wild ricochet) legacy's allure (better cards out there to mind control something) vapor snare (you have several mind control auras already and this one has an unnecessary drawback) think twice-lots of other better draws exist out there in blue
Maybe consider Venser's Journal? It's another card that helps with hand size. And if you end up with 20 or more cards in your hand again... well, you know.

Been thinking about writing a primer for this deck since I play it so much - Watch this space!
mirror sheen (out of the few spells out there that target players, people will decide to not target you...there are better cards to take advantage of this in R/U-redirect, counters, twincast, wild ricochet)
legacy's allure (better cards out there to mind control something)
vapor snare (you have several mind control auras already and this one has an unnecessary drawback)
think twice-lots of other better draws exist out there in blue
It That Betrays (for its high CMC, doesnt really fit with the rest of the deck...you don't make other ppl sac with anything else)
adds:
urza's blueprints (a better jayemdae tome)
conquering manticore (may even want to replace one of the "threaten" cards with this one)
word of seizing (amazing card, split second is not to be underestimated in EDH, even casually...lol)
Tolsimir Wolfblood G/W
Cryptic Command is an all around good card
Desertion is nice against a lot of cards
Stroke of Genius is another draw X spell (only instant speed)
Blatant Thievery is fun in multiplayer
Nucklavee
Flametongu Kavu
Mulldrifter
Draft my Cube!
Played a five player game tonight and won, beating all the other players at the same time using Insurrection
Double Negative to replace Convolute
10.) No taxing cards.
If i wanted to pay 1 more on my Fresh Volunteers, then id just have played Pearled Unicorn.
Treachery looks great but I'd probably replace Volition Reins
[CARD]
Double Negative[/CARD] is awesome, need to get hold of one.
On a trade break. Getting ripped blows...
