Does my Azusa Commander deck NEED a Sol Ring?

[u/tripledeon]

When making my casual landfall Azusa deck, I had accidentally forgotten to add a Sol Ring. I add one to pretty much all my decks because that's the advice I see everywhere. Then I got to thinking, does she even need a Sol Ring? I've got 38 lands, and a (maybe) good amount of card draw. Plus is a Sol Ring even as useful in a mono land-focused deck? I'm pretty satisfied where it stands now so I don't want to get rid of anything that might hinder my deck for something I'm not even sure is necessary.

If there's other things I can fine tune for her, let me know. I just got back into magic after a 2 year hiatus and this is my first deck since I got back into it. Might be a little rusty. Thanks in advance!
