What's more fun than attacking with an army of tokens? Sacrificing them after to blow everything up! This deck is designed to amass a large army and use that army to set people on fire.
It's meant to be played casually for both 1v1 and free for all (though usually free for all) without having to sideboard much (hence the three card sideboard). It's done well in testing, and has shown to have a large variety in play style.
Hordeling outburst, tempt with vengeance, young pyromancer, and krenko, mob boss make an insane token army.
Cards like Purphoros, massive raid, furystoke giant, and burn at the stake let me deal direct, massive damage, which can often be doubled by quest for pure flame or increasing vengeance/reverberate.
Goblin bombardment works to protect from bile blights and detention spheres, provides excellent control and finisher potential, and allows me to at least burn in response to board wipes, and also combos insanely with furystoke giant, chandra's spitfire, and goblin sharpshooter.
Shrine of burning can be put down at the start of the game and finish players off in one hit (combined with quest for pure flame I've dealt 30 damage for 3) and threaten people to do what you want.
Goblin sharpshooter destroys the mirror (as well as elves) and becomes insanely overpowered when I have a lot of tokens, especially with goblin bombardment out or after a furystoke giant (taps for two damage instead of one).
Chandra's spitfire can get insane in a free for all with things like purphoros and shivan gorge (in a four player game, purphoros plus spitfire plus hordeling outburst equals a 28/3 flier on turn five).
Classic burn spells like lightning bolt and stoke the flames provide some extra control.
Finally, sulfuric vortex and skullcrack are sided in against lifegain.
