How do I tighten up my Toph, Earthbending Master Deck

Hey guys!

I am looking to tighten up my Top, Earth Bending Master deck.

Here is the deck list right here https://moxfield.com/decks/kkt5g7LA_E6dH0qdmvSK7Q

Some cards I am thinking about are liege of the tangle, Ouroboroid, and the one ring.

What are some thoughts on the list so far? What can I cut, and put in to make this a little tighter in play.

Any help would be greatly appreciated!
