Oran-Rief, the Vastwood, Wayward Angel, Sprout Swarm (much better mana dump than selesnya guildmage), Gavony Township. Don't run back to nature if you're gonna run 10 enchantments. I have no idea why you'd need crop rotation if all you have are basic lands so that doesn't need to be there. Hero of Bladehold will probably just die if you ever attack with it so I think its a wasted card slot. Finally, why run triumph of the hordes when you can just put in Craterhoof Behemoth? Other than that I think it looks pretty fine.
Didn't see Oran-Rief in your maybe board. Still should be main-boarded.
Looked up ruling you can't play wayward angel because it turns black. Only a little different from Garruk, but same concept. My mistake.
Oh, and Marshal's Anthem is one of my favourite token buffs since you can also return creatures to the battlefield with it. How sweet would it be to return a card like Avenger of Zendikar for a second go? I use the anthem it in the The Knights That See Knee deck.
