Planck units, a Rare card
In particle physics and physical cosmology, Planck units are a system of units of measurement defined exclusively in terms of four universal physical constants: c, G, ħ, and kB.

Ranked #1,651 of the 3,000 cards of the base set by power (ATK + DEF).
The facts on the card
The card carries these facts from its Wikipedia article.
- Expressing one of these physical constants in terms of Planck units yields a numerical value of 1.
- They are a system of natural units, defined using fundamental properties of nature rather than properties of a chosen prototype object.
- Originally proposed in 1899 by German physicist Max Planck, they are relevant in research on unified theories such as quantum gravity.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Planck units article was read about 340,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 71: each hit it takes is cut by 28 %.
How to get Planck units
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.
