My first suggestion would be Necrogenesis. If you spend the time to put them in the grave might as well make them useful right? Just use your unspent mana whenever you need a chump block or when they try to fish a creature. :) My second suggestion would be to try some more creatures, especially ones that gen more creature. You'll love Dragon Broodmother not only does she gen a dragon each turn but the next one can send the first to the grave and buff itself and Kesh all in one go.
Might I suggest Prototype Portal or Thopter Assembly.
Contagion Clasp may be a good choice or Steady Progress for an extra draw.
Have you thought about Unwinding Clock. It'll untap your forge and all your golems on your opponents turn. Plus it works well with things like Palladium Myr and Everflowing Chalice. Here's my Golem deck as well. It works more off proliferates but maybe you'll see something you like. http://www.mtgvault.com/ViewDeck.aspx?DeckID=186947
