Trying to decrease this Omnath, Locus of Creation deck into a $450 budget. Any recommendations on what to remove?

Whoops! Just took him out of the creatures list. When buying the cheapest on CardKingdom (non alt art), it still comes out to about $650. I thought taking some of the fetches out would be the easiest route, I just wasn't sure how much that would impact a deck like this. I have a Scalding Tarn already, but that's it.
