The facts on the card
The card carries these facts from its Wikipedia article.
- Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets, though a rotary mass driver has also been proposed.
- Sequential firing of a row of electromagnets accelerates the payload along a path.
- Although any device used to propel a ballistic payload is technically a mass driver, in this context a mass driver is essentially a coilgun that magnetically accelerates a package consisting of a magnetizable holder containing a payload.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Mass driver article was read about 82,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 48: each hit it takes is cut by 19 %.
