I've been running her as a thematic commander for a while now (old decklist video here).
I don't actually like the idea of forcing a tribe on her. A very long time ago I ran her for tribal wurms but it just ended up being 5color good-stuff with 30ish generic creatures, and I lost interest very quickly. The thematic variant although has been one of my favorite decks to play for more than a year now.
