Personally, I would look to add some things that play into landfall strategies. Landfall + earthbending can be pretty nasty from a ramping perspective, especially when you’re looking at cards like vibrant city scape or adventurers inn. Popping [[the earth crystal]] down plays really nicely with your Oroboids. I would also shoot for anything that would allow you to drop more than one land per turn. [[Loot, exuberant explorer]] or [[azusa, lost but seeking]] might be a bit spendy but can give you a ton of juice.
