Interesting take on the steam golem idea. Still, if you're going up against AI3, a lot of defense is unnecessary. Also, trying to grow Golems and use Trident on an Earth mark and two pends won't be enough. You're better off running a couple of gavels for higher damage. Why no rage potions?
In general, I think that steam golem is a rush deck, and adding defense will just slow it down. I wouldn't mind seeing any mods you come up with, though.
