Omen of Fire

Two attacks bolted into a single instant, each aimed at a different color. The first clause bounces every Island on the battlefield, a tempo-and-counterspell tax that strips blue of its lands without distinguishing friend from foe. The second is the cruel half: a sacrifice scaling with white commitment, so a board built out on white permanents must feed the sacrifice a Plains or white permanent for every white thing it controls. The deeper a player is into white, the worse the bill. Instant timing sharpens both halves beyond what the rate implies. Held up, it answers an opponent who has just tapped out to develop, and it can sweep a freshly resolved row of white permanents at the moment they were supposed to stabilize the game. The symmetry of the bounce clause and the five-mana price are what hold it in check: it returns your own Islands too, so it cannot quietly hide in a blue-adjacent deck, and the cost demands certainty that the two colors across the table are the ones being punished. It belongs to a now-mostly-retired design school, cards engineered to wreck specific archetypes by name rather than to earn a maindeck slot on their own merits, written in an era when answering a strategy and answering a color were treated as the same problem.
