your deck is not that great but then again I have no idea about your meta game who you are playing or what kinds of decks or anything. At least where I play or have played that deck would have not done well no matter how well you play it. It is based around to many things and Chaos + beatdown+ control could easily beat it.
not too bad but you donīt have a lot of low level monsters which i like (Too many sacs) but y am i writting this i know for a fact that you deck is bound to have changed since then!
