6/4/15:
Remove 3x Brimaz, add 3x Seeker of the Way
Remove Chained to the Rocks from sideboard
Remove 1x Plains, add 2x Wild Slash
Move 1x Outpost Siege from main to side
Remove Deflecting Palm from sideboard.
Remove Barrage of Boulders from sideboard.

Anger of the Gods in the sideboard?

7/16: Week of Origins release
Switch out Hordeling Outburst for Dragon Fodder?
Possible Origins additions:
Consul's Lieutenant
Kytheon's Tactics
Sideboard: Smash to Smithereens
Abbot of Keral Keep
Goblin Piledriver
Ravaging Blaze (sideboard?)
Subterranean Scout (with Rabblemaster)

8/3: testing removing 2x Barrage of Boulders from sideboard and putting in 2x Deflecting Palm. Possible trick against Nantuko Husk / Rally, also works against Ensoul Artifact, but not as well.

8/6: switching 2x searing blood and 2x valorous stance to/from sideboard. Also trying out 3x Abbot instead of Hordeling Outburst and 2x Exquisite Firecraft in place of 2x Stoke the Flames

8/7: I don't think Abbot is good. Often it exiles something I can't play. Putting Hordeling Outburst back in.
