Can anybody give me some suggestions to help round this deck out more?

I've made a Treasures deck, and it's basically me taking the skeleton of an old Prosper deck and adding in some Smaug and Hobbit based spice to it.

The losses have happened due to drawing far too many lands, and in general - is cutting extra lands worth it in a deck that can consistently generate so much Treasure?

Does anyone have any suggestions for cuts and additions? Some context why would be great but not expected.
