This commander usually comes out of nowhere and ends the game with a damage doubler on board
In Dinosaur-centric decks like Gishath, Sun's AvatarGishath, Sun's Avatar, you could use it to fetch up the brand new Ghalta, Stampede TyrantGhalta, Stampede Tyrant to spill your hand full of creatures onto the battlefield, and create an instant army, or grab Etali, Primal ConquerorEtali, Primal Conqueror to get some free spells
Another use is other sacrifice lands like Wasteland or Ramunap Ruins or Scavenger Grounds and get another crack from this
This deck also made me appreciate the heck out of Corpse Dance, a card I rarely played with before but I think is legit good, its repeat instant-speed reanimation that gives the creature haste and while it does exile at end step, you can avoid this by just sacrificing the creature beforehand
when that land dies or is exiled, it returns as a tapped noncreature land
