How does this deck win? It has almost no damage.
Also, make it two hourglasses (four when doubled). That should be fine really... decent chance for it to draw one in the first five turns or so, and it should be able to fuel it with supernovas. If you had more then it might waste all it's time quanta just playing the hourglasses.
Can't believe I didn't think of this... on top of those hourglasses, add sundials. Six (12 doubled) would be great with this deck.
Unfortunately you still have the damage dilemma.
