A dinosaur in Rivals of Ixalan Standard

I 've played a GR dino deck a few weeks before, casually.

With mana dorks, burns and fatties, the deck isn't weak at a glance. But what expelled it from the competitive band of decks? It can't come back after a Fumigate or Settle the Wreckage. 

I tried to solve the puzzle by putting Duress, Liliana, Nissa, Vital Force, Vraska Relic Seeker. None of them provided me with an effective way to survive through Fumigate in most UW/Token decks. Nor any of them helped me race over fast attackers in Energy/Ramunap Red.

After Rivals of Ixalan, things may change in favor of Dinosaurs, I hope.

Though I couldn't find many good dinosaurs at this moment, I think highly of  these cards:

Thrashing Brontodon
Thunderherd Migration
They all start with "Th"

And this card:

Journey to Eternity, a graveyard card, reminds me of some tool-box strategy.
But when I was writing this line, I was diverted to a direction far from "tribal aggro", once again.

I was starting to build something like these:
Thrashing Brontodon + Induced Amnesia



Journey to Eternity + Riverwise Augur/Ravenous Chupacabra



To trigger Journey to Eternity, target your Riverwise Augur or Chupacabra with a Channeler Initiate:


I started to wonder how funny and sometimes comical or even ironic life is. Whenever I try to build a tribal deck, I end up building a deck with only 1 copy of creature from that tribe.

The deck looks like something called "the Rock" (GB deck with hard disruption) in the past:
2     Duress
4     Channeler Initiate
2     Kitesail Freebooter
4     Thrashing Brontodon
4     Ravenous Chupacabra
4     Riverwise Augur or something else

2     Vraska, Relic Seeker
2     Search for Azcanta

4     Journey to Eternity
8     any cards you like

You can always cut the Duress/Freebooter for more removals or even counterspells. One or two Carnage Tyrant/The Scarab God may also be added as finishers.
