GREEN/WHITE STANDARD WAR OF SPARK !!!

I'm trying to build a standard white/green deck that would still be legal after the 2019 september rotation with mostly cards from War of the Spark so if anyone have any idea how to improve this deck let me know please

So I'm gessing you want to play some form of selesnya midrange/control based on planewalkers deck according to the mana cost of your deck.
Huatli, the Sun's Heart don't do anything usefull in your deck.
Beside Huatli and Gideon, nothing buff your Ajani's Pridemate.
The Charmed Stray are just janky.
Oketra ad Gideon deserve a second card I think, Nissa a third.
If you want to control the board to place safely your walker (which I assume it's you want), some sweeper like Cleansing Nova or Settle the Wreckage should be included.
I might want to advice more, but I feel like I've pissed on your stuff enough already. X)
