This aggressive deck plays Champion of the Parish, Mayor of Avabruck, and Thalia's Lieutenant as human lords to rapidly create an army of large humans. Role-playing humans which speed up your board development and slow down opponents interaction include Burning Tree Emissary, Lightning Mauler, and Thalia, Guarden of Thraben. Kytheon, Swiftspear, and Thraben Inspector round out the thirteen one drops. Burn spells in Lightning Bolt and Atarka's Command can end games on turn three against an opponent who cannot interact.
Your fastest draws involve flipping Kytheon turn two with the help of Emissary into Mauler, or growing your turn one Champion into a 4/4 on turn two with the help of Emmisary/Mayor.
I have streamlined the maindeck to be faster and setting up an ability to play slightly longer and more tempo-based after sideboard against midrange and other aggro strategies. You shave on your Emissaries, Maulers, Avabrucks, and Swiftspears to bring in more removal/protection, midrange threats in Ranger of Eos,Thalia, Heretic Cathar, and Restoration Angel. Inspector and Renegade Rallier provide some resilience and modest card advantage for grindier match-ups. Selfless Spirit and Thalia in combination can lock out control opponents from casting their wrath on time.
