G/B Aristocrats/Tokens/Emerge
The Blood Brothers are Zulaport Cuthroat and Bloodbriar. Think of them like a reverse Soul Warden and Ajani's Pridemate. Your opponent will be reluctant to waste his removal on either, and you'll make him regret it.
Bone Splinters is cheap removal that synergizes well. Nissa, Voice of Zendikar pumps out a token each turn. Eyeless Watcher and Catacomb Sifter provide tokens that ramp, and multiple scry triggers in a single turn off the Sifter can easily set up the win.
There's a lot going on in this deck, but it can set itself up for some devastating plays.
Ex:
Turn 2 - Zulaport Cuthroat
Turn 3 - Weaponscraft Enthusiast (Create two servo's)
Turn 4 - Distended Mindbender (Emerge off the Enthusiast. Force your opponent to discard their 2 best cards)
Turn 5 - Voldaren Pariah (Sacrifice the Enthusiast and the two servo's, your opponent sacrifices three creatures - which is usually his entire board)
Ex2:
Turn 2: Zulaport Cuthroat
Turn 3: Bloodbriar
Turn 4: Eyeless Watcher (Create two scions)
Turn 5: Decimator of Provinces, Bone Splinters (Sacrifice a scion for mana, and another for Bone Splinters to remove a blocker. Emerge off the Watcher. Swing for 19 trample damage, plus 3 damage from the Cutthroat.)
