Thoughts and feedback would be appreciated. I saw a deck on another site and then added the "Defend the Hearth" for a little protection from swarm decks.  Haven't decided if I should sideboard it yet. Added some sideboard burn to protect from creatures. Are there any substitutions in theros or born of the gods for the stuff from the ravinica block since that goes out this fall.  I'd like to get a little more "milage out" of this deck if I can.
