Loop antenna, an Uncommon card

The card carries these facts from its Wikipedia article.

• Loop antennas can be divided into three categories: Large loop antennas: Also called self-resonant loop antennas or full-wave loops, they have a perimeter close to one or more whole wavelengths at the operating frequency, which makes them self-resonant at that frequency.
• Large loop antennas have a two-lobe dipole like radiation pattern at their first, full-wave resonance, peaking in both directions perpendicular to the plane of the loop.
• Halo antennas: Halos are often described as shortened dipoles that have been bent into a circular loop, with the ends not quite touching.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Loop antenna article was read about 37,000 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 74: each hit it takes is cut by 30 %.

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.
