The facts on the card
The card carries these facts from its Wikipedia article.
- This gaseous mixture is used for torches to process refractory materials and was the first gaseous mixture used for welding.
- Theoretically, a ratio of 2:1 hydrogen:oxygen is enough to achieve maximum efficiency, in practice a ratio 4:1 or 5:1 is needed to avoid an oxidizing flame.
- This mixture may also be referred to as Knallgas, although some authors define knallgas to be a generic term for the mixture of fuel with the precise amount of oxygen required for complete combustion, thus 2:1 oxyhydrogen would be called "hydrogen-knallgas".
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Oxyhydrogen article was read about 32,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 61 and blocks with 47: each hit it takes is cut by 19 %.
