Might want to try making it smaller. You may not have lost with it yet, but I can almost guarantee that against a specialized 30 card deck, you might get some wins, but you'll have a lot more losses. Most games would end within eight turns.
If you're only using Brimstone Eaters for Fire Quantum, you might as well just use Burning Towers. They produce more quickly, and are less likely to be destroyed. If they are meant to be dealing damage, too, then leave them, I guess, since it does add up, but they are nice Otyugh and Boneyard fodder.
You might want to replace the Gravity Forces with Elite Otyughs, since Momentumed creatures don't hit Pulled creatures. I'd personally take out the Titan for a Firestorm. Sure, Titan is nice, but getting it stolen can be troublesome, as that's eight damage a turn that you just can't stop.
I'm not really sure exactly what you could do to make this deck smaller without completely reworking the deck, but there's some advice.
