My take at a RG Dinosaurs deck.
I've considered splashing white, and although naya dinosaurs have some pretty flexible options, and some quite strong, I've decided that RG provides the best experience.
The deck is a pretty standard dino ramp, with otepec huntmaster and drover of the mighty coming into play to get an early monstrosaur or regisaur alpha. With a nice opening hand, you can get an Carnage Tyrant as soon as turn 4, and it's pretty much game over for the opponent, a Vanquisher's Banner and a Rhonas's Monument for extra oomph.
Huatli and Samut are still in the 'maybe' area; Huatli, Warrior Poet strongly suggests an Enrage heavy deck, and we have only 2 creatures with this mechanic, 3 with the sideboard. And Samut, the Tested is rather weak by itself, but it can be really powerful with it's ultimate.
I've considered Hazoret the Fervent for this deck, but it doesn't synergize well with it, especially considering we run Ripjaw Raptors; Rhonas the Indomitable seemed a great replacement.
I've mixed deserts in the manabase, ramunap can help deal those last bits of damage needed to finish off the game, and we can all in with Shefet Dunes/Hashep Oasis.
As for spells an instants, it's still not ready, it's just a couple of burn instants to deal with some blockers or some direct damage, plus 2 Invigorated Rampage.
Sideboarding, 2 sentinel totem for mandatory graveyard hate; 4 ranging raptors if the game demands a more heavy ramp, a couple of abrade and by force to deal with those pesky vehicles and extra pumps.
I'm still a beginner in the arts of deck building, so any feedback is really appreciated.
