G/W Ramp has been one of the most dominant decks in the current Standard format, though many of its best cards came from Battle for Zendikar, which is now rotating out.
This is how I would build it right now.
Let’s talk about what the deck gains and loses with the release of Ixalan.

This is close to Ulamog, with the slight difference that if countered, it won’t trigger and won’t get rid of annoying permanents like planeswalkers. But it does kill all of the creatures your opponent controls, since you’ll include it in a shell where all of your creatures are created by planeswalkers.
Paying 2 less mana is obviously a plus, but isn’t that relevant here.
This Dinosaur is an all-star versus control decks, but it also rules against any kind of deck when played on turn 5.
Curving this into Wakening Sun’s Avatar is just devastating and can close up a game fast.

To add to these two monsters, we get this Naya Dinosaur to make sure that you’ll have enough payoff after ramping quickly.
I still think that Druid of the Cowl will serve well as an early blocker and a ramper. I like it better than Drover of the Mighty since its body is relevant until turn 6 or more, where a 3/3 isn’t that helpful.
Thraben Inspector’s departure is certainly painful, and can expose this deck to a lot of very fast starts if decks like Ramunap Red still dominate, which I’m fairly sure they will.
Desert’s Hold is an early removal spell that can gain you a bunch of life, and it will always be relevant.
The sideboard has a lot of slots devoted to Mono-Red, as it will probably be the most problematic matchup. It’ll also have some more beef to board in against control decks where you need to board out Fumigates and Desert’s Hold.
Eldrazi did a great job in the past Standard. Lets see if Dinosaurs can take their mantle.
