Been working on this deck since the spoiler of Aether Revolt. It is extremely effective against the meta-game and provides answers and aggression to the format.
Drana, Liberator of Malakir - One of the main pieces of deck. She fits to well with Winding Constrictor to be ignored. Especially when you can give yourself an answer to planeswalkers since they banned Smuggler's Copter so that Saheeli Rae can become powerful enough to play. However, there is a much better option for that combo! Getting damage with the Constrictor out gives you option of turning any of your creatures into threats.
Winding Constrictor - The main effect and creature of the deck. The only downfall to this guy is that he will be an immediate target for removal. Some interesting combo pieces with this guy:
Drana, Liberator of Malakir + Winding Constrictor + Nissa, Voice of Zendikar
This combo gets you past Grasp of Darkness for both the Constrictor and Drana. Winding Constrictor + Nissa is great as it is but when you add in a first strike flier you get serious board presence that can alpha strike.
Walking Ballista - You want an immediate answer to anything Vehicles, aggro and Planeswalker nonsense? Here he is. When this guy was spoiled I told everyone at the local shop I play at that this guy will be a main creature in format. Trust me you will see this guy a lot in the upcoming Pro Tour event this weekend! He controls the board and gives you position on a multitude of strategies. In a theme deck like this you get to put counters for free on him once you get going!
Try it out and see how it feels! If you have suggestions please feel free to leave them in the comments!
