Ranked #2,345 of the 2,999 cards of the base set by power (ATK + DEF).
The facts on the card
The card carries these facts from its Wikipedia article.
- A coherent derived unit is a derived unit that, for a given system of quantities and a chosen set of base units, is a product of powers of base units, with the proportionality factor being one.
- This means that any equation relating numerical values has the same form, including the same numerical factors, as the corresponding equation relating the relevant quantities.
- E.g. for kinetic energy, the quantity equation is E = × m × v2.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Coherence article was read about 7,100 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 50: each hit it takes is cut by 20 %.
How to get Coherence
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
