Card Trivia:Cloudian - Acid Cloud
- This card is based on acid rain, in which pollutants carried in gaseous form precipitates into acidic rain, which damages the environment.
- This card's effect reflects this, as this card can harm the "environment" of the field by destroying one Spell/Trap Card after removing two Fog Counters.
- Ironically, rainwater is always slightly acidic during precipitation.
