Your creature only needs to attack and not even connect, and if you dont have anything to spend the extra mana on, you can instead grow the creature or dig for better cards
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
