I've been working on this deck for some time now, trying to figure out how I like it running. My original build did not have Loxodon Smiter, but I am really not sure if its worth changing to have it in the main, or sideboard. And with my current build I am not sure if its as efficient as it could or should be, so any suggestions would be appreciated.

Here is the build I am thinking about below:

I would swap smiter for mistcutter and banishers. Maybe drop courage for something else too.
