A friend and I created this brainchild one day at work without any cards in front of us, I wrote it down and built it after the shift and it blows me away how good at comebacks this thing is. I have played with it for a couple months now and consistantly feel as though I will not win, then turn around from 19 commander damage and 5 life left to win.

The deck has a couple win conditions, a couple really powerful 'walkers, and a whole lot of synergy. The biggest counter to it is very, very, hard control decks and land destruction decks. Other than that I have pitted it against so many other decks and types of decks and it always comes out on top.

Obviously, Niv-Mizzet himself is a winner. A 6/6 flying that refills the hand for only five mana is nothing to shake a stick at. Throw double strike on him and he can kill pretty easily. Ajani Vengeant , Narset Transcendent , Venser, the Sojourner , and Vraska, Relic Seeker are the biggest winners as far as planeswalkers go, though Saheeli, Sublime Artificer carries a lot of weight on her back. Amulet of Vigor + Maze's End + Scapeshift is a pretty easy win, even without the amulet. Proteus Staff is a must in any creatureless blue deck. Revel in Riches + Smothering Tithe are there, but I've never won through treasures, just used them as mana.
