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, Greater Good = draw effects. I still feel like I need more and I'd like a Phyrexian Arena at some point.
Deathbringer Throctar, Grave Pact, Dictate of Erebos, Garruk = creature removal
Ogre Battledriver, Craterhoof Behemoth, Anger, Fires of Yavimaya, boots = haste
Dragon Broodmother, Dragonlair Spider, Awakening Zone, Parallel Lives, Doubling Season, Nath, Avenger= token generation and acceleration
Necrogenesis/DRS = Graveyard hate against opponents, gives me tokens. When extreme GY hate is needed, might sideboard in Night Soil instead or even alongside it.
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, Lotus Cobra = ramp.
Wincons: Tooth & Nail/GSZ -> Xenagod, Craterhoof, etc. Prossh + lots of little guys. Mikaeus + Woodfall/Deathbringer with sac outlet. Overwhelming damage.
Because I haven't actually physically put it in the deck yet, but it's the first change I'm making.
