A few thoughts:
1) Here's a build that might be more to your liking, it has some punch, counters, and also benefits from flying to finish the job: https://deckbox.org/sets/943966. I'd suggest sliding in Dromoka's Command if you have them available as that card literally just should read "2-for-1 your opponent."
2) Looking at your list, I would suggest Courser of Kruphix over Nyx-Fleece Ram to grow Ajani's Pridemate. Toss in 4x Blossoming Sands and you have a wealth of possible triggers to grow the pridemates.
3) Banishing Light should be mainboard in some quantity. Given the overall lack of enchantment removal outside of Dromoka's Command, it is a solid removal option that is quite versatile.
4) In your build, outside of Dromoka's Command, I'm not really seeing the appeal to Hornet Nest. It'll potentially stop more aggro builds, but you're already well suited against aggro with life-gain and the benefit of W/G aggro creatures being larger than most things other colors have.
I hope some of these help. I do think there's a solid G/W deck to be built at the moment, it's just a matter of finding the right pieces. Good luck and keep brewing!
