Skullclamp 7 This is a very tidy little way to turn small filler dorks and no longer needed mana dorks into gas
A common pitfall that I see among newer deckbuilders is a draw towards B/R decks that feature both a lot of burn and a lot of Thoughtseize effects
Who thought this was a printable card
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
Breaking serve in Standard has been one of the most important, if not the most important, aspects to winning and this card is exactly what white needed to be able to do this
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
