This is my first Modern deck, mostly because I loved the Ravnica block and hated to lose it. I ran America burn with RTR block and adapted it to a more streamlined Boros burn now. With 22-23 lands, the deck can consistently deal 20+ damage to the face in about 5 turns.
Numbers:
Average turn by which 20+ damage is dealt: 5.84
Percentage of games 20+ damage is dealt by turn 5: 44%
Percentage of games 20+ damage is dealt by turn 6: 80%
The deck has 2 real modes. The burn spells are obviously the main wincon, however it can come in one of two stages.
Against late-game decks: Hit hard and early. Burn away 20 life as quickly as possible with all the 1 and 2 drop spells. Chained to the Rocks and Oblivion Ring are sideboaded for these decks, to take out any threat that can't be burned away. Searing Blood can be used for mana ramp dorks.
Against early-agro decks: Use the burn spells to keep their board clear! Don't let a threat hit the ground. Once a Guttersnipe or two has hit the board, they are just going to take repeated 2 damage pings every time you burn a creature away. And when they run out of threats, you can move in with a finisher. Satyr Firedancer and Searing Blood are sideboarded so that you can get multi-purpose burn spells against these decks, dealing direct damage and burning a creature.
All feedback and +1's appreciated. Especially related to the sideboard. As this is my first modern deck I'm not certain what I may need to account for or what cards I have to pull from.
