Dies to Removal

I built this deck too after tom ross' awesome performances with it, but i have to say i am not impressed. I mean, i am conscious that i should improve my play because the deck is quite unforgiving -- make a mistake at the wrong time and you just lose-- but what concerns me is the very high mulligan ratio.
I keep getting hands with no creatures, one landers, color screw, all creatures with no auras to start the party. When everything works well, i feel unbeatable, but i would love some more consistency.
