Fog with help you out against faster decks and flying creatures. Though Terra Stomper is really a cool creature i think it's not with the landfall theme. Avenger of Zendikar is awesome in landfall deck. Too many oracle of mul daya, try adding 1 Asuza, lost but seeking. Otherwise good job.

I think it's a nice build. Would be better if you can cut down to 60cards though, maybe take some of the creatures out. Too many grazing gladehart. Avenger of Zendikar is awesome in landfall deck, with scapeshift, amulet of vigor and crucible of worlds you'll be packed with token creatures. I would add some fog into this too because you'll have problems with faster deck and flying creatures.
