Well this should be no surprise, my commander is Zacama, Primal Calamity. 6 R/G/W for a 9/9 with Vigilance, reach and trample. Plus look at the etb. Wow! You can start using his abilities straight away, or cast some other shenanigans from your hand.

With the dinosaurs selected from the ones available from Ixalan and Rivals of Ixalan I’ve tried to go with ones that I can get some sort of secondary benefit from, whether that is from an enrage ability or etb. The non-dinosaur creatures that I have gone for are there for ramp. They either allow me to tap them for mana or give me a discount on casting dinosaurs. Naturally having the two Hautli Planeswalkers is a given to. Although I haven’t actually managed to draw one yet in the 4 games I have played with this deck.

I do have a few mana ramp spells, which I think are needed big time in this deck considering the cost of those dinosaurs to cast.

Here is the graphical stuff that the Decked app produces.

I’m pretty surprised you that AMC. Thought it might be a little higher than that.
