1. You have excelent taste in music!

2. I would take out the Gaia Power. Even though your deck is mostly Earth they can be terrible draws if you start top-decking. At least take out one.

3. Add in something to help you cycle through your deck a little bit. Either Card Destruction or Mirage.

4. Add in one more Enraged Battle Ox and Sinister Serpent.

5. Since you seem to have a trample deck, I don't think that you need the Nobleman of Crossout.

Its not trample. Its earth beat. o.0

VoC!!
