I wanted to make this too, I’d cut the Ghaltas and/or Gigantasouruses to add 4x God-Eternal Rhonas and enjoy the repeated ETBs powered by Ilharg. I’d also use the space made by the suggested cuts to add 4x Domri, Anarch of Bolas for Ramp, Buffs, and the occasional upside against control (note it reads “this turn” and not “cast with this mana”).

Add the Dominaria duel lands as well as the shock lands from Ravnica and drop the playset of Circuitous Routes for one of Steel Leaf Champion . Between the Llanowar elves, the Icubation Druids, and the Multicolor lands you can cast them worry free.

I don't think you're gonna want 4 copies of each god. Not only are they legendary, but they already recur on their own maybe 3 would work, but I'd even recommend going down to 2 of for each and adding some other good stuff

It’s just that important to have on you. But I see your reasoning. I’d go for 2.
