Feedback, an Uncommon card
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause and effect that forms a circuit or loop.

Power 152 (ATK + DEF): stronger than 75 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- The system can then be said to feed back into itself.
- The notion of cause-and-effect has to be handled carefully when applied to feedback systems: Simple causal reasoning about a feedback system is difficult because the first system influences the second and second system influences the first, leading to a circular argument.
- This makes reasoning based upon cause and effect tricky, and it is necessary to analyze the system as a whole.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Feedback article was read about 100,000 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 75: each hit it takes is cut by 30 %.
How to get Feedback
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.
