Synergies with mana generators: Cards like [[Culling the Weak]], [[Infernal Plunge]], [[Phyrexian Tower]], and [[Mox Amber]] shine with [[Rograkh, Son of Rohgahh]] in the command zone
Some good Gruul commanders definitely show up, but I try to highlight cards that also play well in the 99
Coati Scavenger is a textbook enter-the-battlefield trigger
Considering this card has an acorn holo-stamp, Im not sure in which format you can assemble it with the Tron lands exactly (maybe with the help of the aforementioned Photo Op?), but if you do, you literally have infinite mana to play with, and victory is just a Fireball away!
It synergizes best with and haste enablers to make sure you get that attack in quickly, and other sources of lifegain to ensure you rattle off a bunch of spells when you do
And thats good because Im sure Wizards could put their foot down on the power pedal a little more if they ever return to the card type
