Chain Reaction (C18-121) is a red sorcery reprinted in Commander 2018 that deals X damage to every creature. X is equal to the total number of creatures on the battlefield at the moment it resolves, potentially functioning as a mass removal that scales with board size. This card is typically used as a symmetrical board wipe or a finisher in creature‑heavy metas because its damage grows with opponent and ally creature counts.
