Hi, and welcome to the forums!
It looks like a decent mono-fire deck. You've got a good balance of quanta, forms of permanent control and creature control, as well as heavy damage. However, all of the things you put here are quite expensive. Consider replacing a few cards with less expensive alternatives. For example, dragons with phoenixes (cheaper cost, more survivable), using other forms of creature control like fire bolt (direct damage capability) or rage potion(faster and better for single targets)-- a little more versatility never hurts! Don't be afraid to mix things up or fiddle around!
Also, what opponents are you currently using it on/trying to focus on? It's been a while since I've been playing a lot, but from the looks of it you've got the beginnings of a AI-3 farmer.
This (UTAlan's QI calculator) is a good tool for calculating your quanta balance while you mess around with stuff.
We also have a wide variety of tutorials and guides
here that can be very useful in all sorts of elements related stuff, deckbuilding included.
