Also 6 Fractcals is too many. Drop 2 and a Pillar and pick up a Lobo and a couple of Lightnings to deal with enemy Otys and other threats to your Gemfinders.
This.
Finally, somebody made a Gemfinder fractal!

Congrats on making this. It looks sound to me. Essence's suggestions are what I would suggest, too.
Do you think this deck would work better, or the fire rush with brimstone eaters/fahreinheits?
For what?
Overall, the fire rush is definitely better, though.
