Blazing Volley

One mana for a single point of damage to each creature an opponent controls is the sweeper at its most surgical: it kills the swarm and leaves your own board untouched. That asymmetry is the entire point of the design. Symmetrical pingers like Pyroclasm hit everything; this one carves out only the other side of the table, which makes it a clean answer for a go-wide aggressor who has committed a row of one-toughness bodies and needs them gone without sacrificing their own attackers. The cost is breadth. One damage prunes tokens and mana dorks and the cheapest hatebears, but stops cold against anything with a second point of toughness, so its ceiling is dictated entirely by what the opponent has chosen to flood the board with rather than by your own play. That makes it a reactive, matchup-dependent piece: dead against a midrange creature deck, devastating against the swarm it was built to punish. It belongs to the lineage of narrow, color-pie-honest red effects that trade flexibility for a price tag so low it barely costs a turn, a one-mana lever you hold specifically for the games where the opponent's plan is more creatures than yours can profitably block.
