Easily the most fun I've had using red mana. The only downside to this deck is the strategy is pretty much "attack, burn, or both". Elegance in simplicity I suppose; the purpose is to turn every available mana source in to damage via the Hatchling or Stonewright while clearing the way for attackers.
Hound of Griselbrand is still a champ that presents a big threat and can't be put down easily which usually nets me some card advantage if my opponent is committed to getting rid of him through non-exile based removal. Another contender for 'finisher' is Charmbreaker Devils what with their ability to return removal to my hand which pumps up said devils.
SIDEBOARD
Annihilating Fire - to pitch undying creeps into exile along with anything else i don't want to see turning up anymore. Likely replace Brrimstone Volley for this to keep curve steady.
Archwing Dragon - He's here if I find a lot of sorcery speed removal or run into Death's Hold which would kill anything else, but turns him into a 3 burn for 4 mana (hopefully). Sideboard the hound for this.
Blasphemous Act -a board sweep to deal with tokens. Hopefully it'll be cheap to cast and i won't have everything on the table at the time.
Forge Devil - pop a mana dork or any other utility creature I don't like. He'll probably only see play against a white weenie or a ramp deck where i don't want to waste a stronger burn on a small creature.
Reverberate - just fling counterspells right back at whoever sent'em. That or possibly just double the burn if i think it'll go the distance. Maybe even keep the board balanced by copying a token spell or something spell.
