Forum:Macro Mill - Help Please

I built this Macro Mill deck and it's pretty good already, but I was hoping for some tips to make it better. Any advice is welcome.

Total: 42

The point of this deck is to destroy the opponents deck using Necroface and the Worm monsters. I also include D.D. Scout Plane and Soul Absorption to take advantage of Macro Cosmos. Cyber Valley and Chaos Zone allow me to recycle the effect of Necroface. Obelisk The Tormentor is more of an incidental card, but given the relative ease of summoning monsters to the field, it can be a useful addition.

Any other suggestions would be welcomed.
