    Chrome Mox was banned in brawl on November 10, 2025. Chrome Mox and Ancient Tomb fall into a similar category. Both are colorless mana accelerants that cost no mana but ask you to pay some other high-polarity cost; either a card or life. In the spirit of keeping Brawl more casual, they are banned.
