Turn 1: discard two {elvish spirit guide}s to play {channel}. Pay 15 life for 15 colourless mana and drop the big one {emrakul, the aeons torn}
I have this in a casual deck and after we both draw seven cards my friend asks me 'have you got it?' And if I do I say yes, show him and he concedes. So technically a turn zero win!!!
A {chancellor of the tangle} in your opening hand plus a green mana would work as well without discarding. Not sure if that has better odds or not though.
Anyone else notice that the mana->life card is only online? No physical copy... DARN IT!
Belay that last, I'm going to the store now to buy 4, I already have 2 emrakul!!
