Cool deck idea, I have a deck similair to it Izzet Spellsplosion, but if you'd be willing to let this deck go later, Charmbreaker Devils are awesome

Nivix Cyclops. I'd want 4

Gitaxian Probe, Mutagenic Growth, Assault Strobe, Artful Dodge

i enjoy the ideas of both gitaxian probe and assault strobe thanks for the recommendations!

This is a very nice deck, but maybe add a little more kick to your fire. Ral Zarek kinda fits the theme in this deck, plus, he's a planeswalker. Cards like Dominus of Fealty and Essence Backlash can really make this deck one to be weary of. Crackleburr can be useful if you really want to annoy your opponents, and to top it all off, Goblin Electromancer will speed things off, as well as Hypersonic Dragon and Inside Out.

Very nice, +1 to you. I'm an Izzet player by heart and can tell this would be a blast to play.

As for Unkn0wnz comment, Goblin Electromancer and Inside Out are nice cards, but for this deck I'd disagree. With Electromancer you only have a total of 3 cards to reduce cost and Inside Out has always been more fun manipulation with a cantrip which I don't think serves as much of a purpose as Vapor Snag or Electrolyze.

Only suggestion I can think of might be a Stoke the Flames or two, esp. if you have a good start with some Pyromancer tokens.

Thanks for the suggestions, I may add one or two Stoke The Flames depending on how they test. It is a very nice card and goes very well with pyromancer, however it would hinder other cards like Swiftspear and Kiln Fiend if i needed to convoke it.

Well, if we're going into Izzet, then Izzet Guildmage and Izzet Staticaster would be a perfect fit to this deck. Magefire Wings could be useful for certain creature in this deck like Monastery Swiftspear, and let's not forget about Melek, Izzet Paragon. Plus, Mindwrack Liege isn't really Izzet themed, but who wouldn't at least consider it? Last but certainly not least, Mirror Sheen could finish off an opponent. I rest my case.

Also, why have Shivan Reef when you could have Swiftwater Cliffs?

Because Swiftwater Cliffs slows the deck down when this deck is about tempo and aggro
