Aggro-centered creature beatdown with lots of haste, trample and pumps. Turn 4/5 win or bust.
Let's break it down, from the bottom of the curve to the 4-drops:
Elvish Mystic: Mana ramp? In an aggro deck? Yeah. A turn 2 Groundbreaker is no laughing matter, and having 1 extra mana available can always help you to squeeze in a combat trick or a Fog. He can also be pumped and deliver damage when all else fails (opponents mostly won't be wasting removal on one little elf). Finally, chump blocking should give you the advantage against other aggressive decks.
Uktabi Drake
: The footman. Deals beatings early on or can also deliver the finishing blow directly thanks to his flying.
Rancor: Best green aura ever printed. Has special synergy with this deck because cards with echo and Groundbreaker will be dying a lot.
Vines of Vastwood
: +4/+4 and hexproof (kinda) for 2 mana is pretty insane. Also, you can target your opponent's creatures to prevent them from being buffed. Also, this is a common.
Giant Growth: All-purpose pump and combat trick. Feel free to mix them up with Primal Bellow if your opponent is stalling the game.
Primal Forcemage: With almost every creature in this deck having haste, this guy becomes a huge threat. It basically demands an immediate response from the opponent.
Dungrove Elder,
Timbermare
and Vengevine: The finishers. Dungrove is particularly helpful because, unlike the rest of the deck, he grows more powerful as time goes on. He is difficult to deal with, and by the time you put him on the table your opponent should've spent most of his removal/cleanups on your lesser bruisers. Vengevine acts similarly, coming back from the dead time and time again thanks to cheap creatures.
The sideboard is pretty intuitive. Fog against other aggressive decks. Harmonize for when you need more staying power. It's good against decks with lots of boardwipes. Beast Within deals with problematic artifacts/planeswalkers or even creatures. Finally, Savage Summoning is a great card against blue control.
