Avenging Arrow

In Commander, Avenging Arrow earns its slot in white decks that deal incidental damage through pings, combat, or activated abilities — the setup condition is trivially easy to meet in a multiplayer game where blockers trade and damage flies constantly. In Pauper, white removal is competitive enough that Avenging Arrow rarely beats out options like Disfigure or Prismatic Strands for slot efficiency, though the unconditional destroy effect has niche appeal. Modern and Legacy have removal bars too high for a three-mana sorcery-speed conditional instant to clear. Oathbreaker mirrors Commander's logic — if your planeswalker or signature spell deals damage, the condition snaps on almost automatically.
