Pollutant Gas is a Perseverance deck specific effect card. It deals 1 DMG to all enemy monsters under KR on the board, and will give KR to all enemy monsters afterwards, including those that were summoned from Dust effect triggered by the 1 DMG, such as Rock's Pebble or Snow Poff's Greater Dog.
Because of this effect, you can combine this with another Pollutant Gas, Contamination, or Asgore in some cases.
