Pump. Wins. Games.
Turn 1, the second most important turn of the game, Preferabley drop Stromkirk Noble.
Turn 2, Drop 1-2 Burning Tree Emissary and free cast Flinthoof Boar, the more creatures you get on turn two the more damage you're doing on turn three, say you didn't go first and you're facing aggro, use Burning Tree to freecast Searing Spear, or to put Volcanic Strength on Stromkirk.
Turn 3, This is the turn to decide who wins the game, This is when you drop Flinthoof Boar with Haste, this is when you play Boros Reckoner when they play Thragtusk, This is when you Bloodrush Ghor-Clan Rampager and Giant Growth something else.
Turn 4, Hellrider.
Volcanic Strength, This wins games against any red deck.
Stonewright, Pump creatures when you can't Bloodrush or Giant Growth them.
Ash Zealot, First Strike is great with Stonewright or vs aggro.
Sideboard:
Ground Seal, Anti Re-Animator
Gruul Charm, Opponent not running red? Have fun with unblockable creatures for that turn 4 kill.
Pyreheart Wolf, I've noticed he's harder for mid-range to deal with than Hellrider.
Skullcrack, Anti Turbofog/Life-gain decks.
Traitorous Blood, Good vs Mid-range, since I can't Spear off Loxodon or Thundermaw, might as well use their own creatures against them.
