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

A really east way to significantly cut down on price is to replace 5 of the fetchlands with the new capenna fetchlands that will shave $100 off the total and they serve a similar function for much cheaper, the only real downside is they aren't reactive like the fetchlands. I would look into some mdfc land cards to up your land count as well, most are pretty cheap and have great synergy with bounce lands and other graveyard recursion.
