R - The deck, the deck, the deck is on fire, we don't need no water let the...

Exactly! Let it buuuuuuuuuuuuuuuurn!!!

I present you the deck that is on fire!!!

LANDS - 21
21 Mountain

CREATURES - 10
3 Shivan Dragon
2 Firemaw Cavu
1 Crimson Hellkite
1 Crater Hellion
1 Fire Dragon
1 Scourge of Kher Ridges
1 Shivan Hellkite

SPELLS - 29
4 Incinerate
4 Kindle
4 Lightning Bolt
4 Seal of Fire
3 Fireblast
3 Seething Song
2 Browbeat
1 Beacon of Destruction
1 Leyline of Lightning
1 Planeswalker's Fury
1 Scent of Cinder
1 Steam Blast

I only feel for having only 2 Browbeats in my whole collection. Shame on me since this deck begs for 4 copies of this awesome card.
Apart from that, Lim-Dul made me take into consideration Fling. I might add 4, removing Scent of Cinder, Steam Blast, Shivan Hellkite and Crimson Hellkite.
Most of the deck is thought around cards that deal damage. Lots of damage. Something above the 1 mana - 1 damage ratio per spell.

The Sideboard is as follows:
4 Smash (against possible artifact based decks)
3 Price of Progress (this might be an instant addition to the main deck in the near future though)
3 Flame Wave (are you playing winnie?)
2 Arc Blade (just in case)
2 Guerrilla Tactics (did I hear you say discard?)
1 Storm Entity (not sure if this should be main deck)

Now, did the advanced classes on Aggressiveness paid off?

1 Scent of Cinder
1 Steam Blast
1 Fire Dragon
1 Mountain

were subject of removal from the deck so that I could add

2 Bloodthron Taunter
1 Exuberant Firestoker
1 Desert
