Mardu Brimaz Aggro Manabase: 2 Swamp 1 Mountain 1 Plains This one obviously uses more tapped lands but can support both Brimaz and Heros Downfall, in addition to having red mana for sweet gold cards
Duskmourn added a damage-multiplier, which I gushed about in my Red Set Review, but the Commander Deck one-upped it by adding a hasty, first-striking mana-doubler on a stick that damages players for tapping lands
Second, between Reckoner Bankbuster, Prodigy's Prototype, and Esika's Chariot (along with Mech Hangar in our mana base), most of our Vehicles make creatures that we can use to crew them, which minimizes our need for "real" creatures
In a deck packed with high-impact green cards, thats a massive refill
My first instinct is to throw it into a Samurai and/or Warrior deck and combo it with Raiyuu, Storms Edge, but Commander has a lot of potential ways to keep extending a turn with more phases, and any devoted red player should consider having it in their deck
Every time you're tempted, including the first time, you must choose a creature you control to become your Ring-bearer
