Changed it up.
Took out a few lands and put in more ramp. Perhaps I'll stick in Yavimaya Elder, but he only brings stuff to your hand.
The sideboard is the sideboard that I use for tournaments. Usually lots of recursion from black decks and control from blue decks.
Purposes of various cards:
Beastmaster Ascension, Craterhoof, Ogre Battledriver, Xenagod = increase bigness
Birthing pod, GSZ, Tooth & Nail, Chord of Calling, Genesis Hydra = creature tutoring
Cream of the Crop, Viscera Seer = scrying and draw fixing.
Fecundity, Greed, Skullclamp, Solemn Simulacrum = draw effects. I still feel like I need more so I'd like to get a Life's Legacy in there.
Attrition, Deathbringer Throctar, Goblin Sharpshooter, Grave Pact, Dictate of Erebos, Garruk = creature removal
Ogre Battledriver, Craterhoof Behemoth, Anger, Fires of Yavimaya, boots = haste
Dragon Broodmother, Dragonlair Spider, Awakening Zone, Mycoloth, Necrogenesis, Parallel Lives, Primal Vigor, Doubling Season, Fresh Meat, Garruk = token generation and acceleration
Necrogenesis = Graveyard hate against opponents, gives me tokens. When extreme GY hate is needed, might sideboard in Night Soil instead or even alongside it.
Oversold Cemetary, Charnelhoard Wurm, Eternal Witness, Sheoldred = graveyard recursion
Exploration, Awakening Zone, Chromatic Lantern, Coalition Relic, Into the Wilds, Kodama's Reach, Sakura Tribe Elder, Search for Tomorrow, Skyshroud Claim, Solemn Simulacrum, Xenagos, Farseek, Cultivate = ramp. Want to see about getting a Tempt with Discovery in there too.
Wincons: Tooth & Nail/GSZ -> Xenagod, Craterhoof, etc. Insurrection. Prossh + lots of little guys. Mikaeus + Woodfall/Deathbringer with sac outlet. Garruk. Overwhelming damage.
