Burn will always exist in Modern for its ability to punish slow starts and sneak in free wins quickly. I can see how this deck would provide a good practice for other decks, since its able to apply a lot of quick pressure, but as Kaylesh says, there are a lot of modern cards that do what your cards are doing, only better, or for less mana. The easiest example is
Lightning Bolt vs.
Shock. Lighting bolt is clearly better, as it costs the same as
shock but deals 50% more damage. Other examples of "cheap" burn cards to consider are:
Rift BoltLava SpikeLightning StrikeSearing BlazeSearing Bloodand quite a few more. The same goes for creatures. While
Ember-Eye Wolf is fine,
Monastery Swiftspear does a pretty good impression for a single mana, and generally prowess will be easier to trigger than paying for the wolves ability.
If you took the deck to a modern night as is, and your local shop isn't super competitive, you'll probably do fine.
Odds are the deck isn't tuned enough to win the whole thing, but the only way to know is to try it out.
here's a decent article to look over as a good (and cheap) way to start.
