Well, for starters, it seems pretty decent, but you might want to reduce down to 30 cards (you have 34 currently). I'm not going to tell you what to do with your deck, but I
will mention on what
I would do to improve this deck, if it were my own.
First off, I'd take out the Stone Dragons and the Titanium Shield and the Enchant Artificats. The Earth quantum should really only be used with the golems, and having those other spells really just slows you down.
I'd probably take out most of those Stone Pillars, perhaps leaving two or three max. If I were to take out the other Earth cards, then I wouldn't need so many Stone Pillars, unless I got a few golems out.
I'd likely add some Plate Armors, too, to make the Golems more durable. This will help protect them from early Otyugh or kill spells.
I'd take out the Fire Bolts and replace them with Rain of Fires, for more universal creature control. I would add some more Deflagrations, too. Probably around four Deflags and two RoFs would be good.
Having Hammer and Fahrenheit means that if you have one in play, the other sits useless in your hand. Sure, they could be destroyed or stolen, but neither of them are priority targets for Steal OR permanent Destruction. With the ammount of Fire quanta that you'll be spending, Fahrenheit doesn't seem like a good choice, but because the Hammer gets weaker for someone if they don't have an Earth or Gravity Mark, most people won't steal it. If I were to run a weapon, it'd most likely be JUST the Hammer.
The final deck would probably look something like this:
Mark of
EARTH
With so few creatures, it is a tad luck dependant, but it would most likely work very well against the AI decks, and perhaps decently in PvP.
I hope that helped. =D
