End the Festivities

The control clause is the whole design: rather than the indiscriminate "each creature" that most red pingers carry, this one carves out everything you control and rains a single point on each opponent, their creatures, and their planeswalkers. That one change turns a symmetrical ping into an asymmetric one, and asymmetry at one mana is what makes the effect worth printing at all. One damage is a small net, but it is thrown at a specific school of fish: token swarms, mana dorks, the one-toughness aggressive curve, plus a point to the face as a bonus. Where an ordinary red sweeper forces you to eat your own board to clear theirs, this reads as pure upside for a go-wide or reactive deck, because your side of the table never gets wet. The arithmetic bends further in its favor as opponents multiply, since every one of them and each creature and planeswalker they control absorbs the hit while you sit out, so a single point of listed damage can triple or quadruple its real output. Which card it actually is (a cheap token-wrath, a burn spell, or a slow group-slug engine) depends entirely on who is sitting across from it.
