Might want to throw in Nissa, Worldwaker for all that land and Horn of Greed for card advantage. In case you haven't seen it, That One EDH With 70 Lands would be great for ideas here

Thanks for the comment. Nissa, Worldwaker is a lock whenever I bother to get one. I didn't know about Horn of Greed , though given how popular ramp has gotten among my friends, it could backfire (I'll definitely tell my buddy with the Nekusar deck about it - that, plus Notion Thief would be right up his alley. And man, that EDH deck already has me tingly. Baru, Fist of Krosa and Burgeoning are new to me. Great stuff.

I love you

What about Exploration? It is cheep ramp that help pump your commander. And on that end either Azusa, Lost but Seeking and/or Oracle of Mul Daya to get all the lands into play. But overall, Exploration is the budget option.

Have you considered adding Court of Bounty? Introduces the Monarchy into the game for some card draw, and lets you drop an extra land each turn.
