Since we're a Vehicles deck and all vehicles are artifacts, it makes sense to take advantage of artifact synergies, which I deliberately steered the deck into: we're running all the artifact mana cost discounts from Foundry Inspector to Semblance Anvil, drawing cards off Canoptek Spyder and Sanwell, Avenger Ace, and protecting our board with Leonin Abunas and Bronze Guardian
Theres not really room to have an expanded stack, leading to several tiny items getting piled atop one another
give them the creature, take control of the spell, and let them eat all the damage
Theres an argument that these are better in the 99 than as the commanders of a dragon deck because they offer card advantage when they ETB and fetch the other one from your library
Using prison style decks to keep Azami off mana - infinite or otherwise - and deny other resources to prevent the deck from achieving mass card advantage
Of course, Zanarkand, Ancient Metropolis, and Slime Against Humanity arent the only token-creation effects that can take advantage of replacement effects like this
