I think izzet mill is bad.
You will beat control decks of an average hand, sure.
But vs an average netdeck aggro hand you will just fold, unless you get the mega early tutelage AND the required early burn AND the correct land mixture.
Then you have to hope that nothing stops your wincon, and that you don't flood out, and if you lose control, only displacement wave can maybe save you. At sorcery speed.
It's wishfull thinking.
Sultai mill is viable because of endless fog effects / languishes. In the sultai thread there has been multiple viable builds posted. Izzet is a one trick pony that hopes that everyone plays foundry street denizens and that it keeps drawing twinbolts.
I'd say of an average hand it doesn' t have HALF the staying power of sultai mill.
2/5 on steam at rank 40 (ish, when I lose i allow my opponent the winning swing, I don' t alt f4 cuzz OH NO PRETTY EMBLEM OF RANK).

I'm still messing with it, so far I think geg has the right ideas, the thief is a good blocker in this deck, and avoiding lots of gates will sometimes make your whish upon a star come true. IMO we need some
evacuation or that old red sweeper that does damage to each creature based on the number of creatures in play for izzet to be better than sultai mill.
Hydrolash alone doesn't cut it. Displacement wave is worse here because you can't fog on their turn if they are using haste etc.
BTW geg I really like your sultai mill build. I think it's maybe a bit less reliable than the one I posted because it uses alot of mana for big shiny effects, but it's alot of fun to play
