*facepalm* Why do newer players always try mill? :P
Nothing against you specifically, but it's a recurring theme on here I've noticed. You'll find out through play and experience that it's easier to deal 20 damage than it is to mill 53 cards to win. Nice you were able to put something together though.
I will say this for you though. It's probably one of the most coherent and thought out mill decks by a new player I've seen in a while. I would make a couple small changes, if you have them some essence scatters, over the negates. You're more likely to have trouble dealing with creatures without real board wipes. You should really find some
detention sphere's (or more o rings) and
supreme verdicts when you can, or other board wipes.
