Deck ramps quickly with power stone and wilderness refuge
Been really liking Antique Polisher as it trades with a lot and reduces your relics to play/spellcraft them ahead of curve.
Vapor Hut has also been an MVP in this deck. It runs only 1 as you do want to pull this with Larai most of the time. Hut is a late game card that allows you to get rid of power on the top of your deck and ensures you only draw gas. If you have a Kaspar out, you can easily ramp to 15+ power and have control of the game.
Market
Fearless Crescendo has been my market of choice over Crack the Earth as it allows you to stabilize against aggro by pulling a hailstorm. Getting a 5 drop from the market from Crack the Earth does nothing if you can't stabilize the board. Amber ring to spam units which can get exalted from Grodov Burden. Pristine Light has almost never been grabbed, so could be swapped with something else, maybe Display of Tradition or Turn Back Time.
