Cascade is a powerhouse mechanic in general, but in Commander, it really shines thanks to the plethora of cards on offer
MTG Wiki defines ramp as A card which accelerates your mana, giving you an additional, reusable mana source beyond the usual one land per turn
Wizards of the Coast rarely tells you what that card is ahead of time, and its value can vary a lot
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
Later on, in 2025, Wizards is doubling up with the MTG x Final Fantasy Holiday Release
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
