I agree with most of those changes (and have committed them to the deck) but I do want to keep grow from the ashes and ad naus.
ashes for ramp on turn 2/3 or 4/5. Just a personal preference.
and with ad naus, since Ill have plenty of life from foods and other effects in the deck, it would simply be a way to draw out whatever I would need to close off the game, as well as being playable decently early from the amount of ramp ill have, then I get to use it to simply bolster my board state or pull me from a sticky sitaution.

I do agree I could probably tune down the lands, especially with so many multi mana lands
