B/U Phyrexian Control is geared toward winning via Poison and Proliferate. Land one poison counter on them, and let the machine do the rest. Took this to Game Day and got 3rd place, same deal with FNM a month later. Going to FNM tonight, last one before New Phyrexia shifts the meta, will post results tonight.

ALL THOUGHTS WELCOME
I landed 3rd place at Game Day and FNM, using the beautiful Black Sun's Zenith as a trophy in the deck. It was so fun, I want to take it to FNM again before NPX (though everyone has seen it now, so I lost the surprise) It's posted for feedback, so feel free to give your suggestions!
