When an opponent has tapped out and you have an Atog, you can also sacrifice most if not all of your artifacts to the monster with the best smile around to throw it straight at your opponent with the Fling or overtake their small creature with Temur Battle Rage for a nice clean victory
The rest is a smattering of +1/+1 counter cards like Hardened Scales, as well as some nice staples like Farewell and Three Visits
Last week while sharing my Etali, Primal Conqueror deck and sharing my love of Gruul commanders, I mentioned I had a Kibo, Uktabi Prince deck that was unfinished, in progress as it were
Also, its just a great card
Thats thanks to the Powerstone-aping Vibranium artifacts, which cant be destroyed and can tap for artifact spells
