I like the Lodestone Golem suggestion. It has high enough power for Rhonas/Goreclaw/Surrak, it's easy to cast, and it disrupts the opponent. Sounds better than bending over backwards for Thought-Knot Seer, even though that card is strong too.

Is Okina, Temple of Grandfathers a good 1-of because of your legends, or is it bad because of Wasteland and Blood Moon?

Is Tarmogoyf an idea for this deck, with Deathrite Shaman gone? You're looking for big, dumb, and green, and Tarmogoyf is the poster boy for all of that, but is it big and dumb enough if you don't play cantrips and fetch lands?

The 3-mana slot is hard to fill. Seems like all the best creatures are 1GG. How good is Reclamation Sage turning out to be? Good enough for more than one? The other good 2G card is Tireless Tracker, but that feels like a different direction than the straightforward lock-and-attack plan you have now. Overall it feels like the cards that work the Rhonas/Goreclaw/Surrak angle in a Legacy stompy deck haven't been printed yet. It might help if they weren't all legendary.
