The way you have it constructed, it would seem that you'd be far better off just beating down your opponent rather than relying on the Golem's milling ability.

Have you tried using artifact mana and Denying Wind? I don't know how you're going to force your opponent to block (Coastal Piracy, perhaps?), but if you do, you can do a lot of milling really fast with lots of artifact mana and Denying Wind to back up the Golem. At the worst, you can totally remove all the non-lands from your opponent's deck, and at best, you could deck them. Either way, I think Denying Wind, if you can handle the mana cost, can be a devastating card, and it fits right into the theme of the Golem, too.
