Primal Vigor Another one of the green token doublers MTG has printed is Primal Vigor
Having a way to combo off and generate absurd amounts of mana in the command zone that also has a win condition stapled to it is firmly in the high end of Bracket 3 or just straight up Bracket 4 or higher, based on the cards you end up including in the deck
I don't actually recommend Doubling Season because it's overcosted if you only use half the card More Counters on Themselves: Avenger of Zendikar especially if you add more fetchlands and land ramp, also Taurean Mauler is a worse Managorger Hydra but still amazing with our commander Draw: The Great Henge, Tribute to the World Tree, Esper Sentinel Ramp: Kodama of the West Tree, Defiler of Vigor, Biophagus Protection: Shalai, Voice of Plenty, Deflecting Swat, Bolt Bend, Heroic Intervention, Teferi's Protection, Clever Concealment, Silkguard Combos: Heliod, Sun-Crowned and War Elemental do the same thing as The Red Terror
It's worth it, but you will be spending Energy until end of turn, and that means this is a junk rare
Rooftop Storm $5.98 Rooftop Storm is one of those cards that jumps in price every few years, usually when theres a zombie set or Commander precon printed without it
Skullclamp 7 This is a very tidy little way to turn small filler dorks and no longer needed mana dorks into gas
