In Moon Karts I always like to keep my eye on the market and see which cards are available for sale and how many in Circulation that are available and this gives me a good idea of the importance of each card, and which rare cards may become powerful or expensive in the market next time when I want to buy it and this is good for me.
If we look at this image, we see that there are very few cards in circulation. For example, Blaze, which has an astronomical price of $749, is only available in Circulation 5 and this is a very small number, meaning that the card is very rare and likely highly played, or sought after for its value.
Also, there are only 11 of Arachno Eclipse cards, and it costs $200, which also demonstrates its rarity and value. Next is Luna, which has 12 of them and is priced at $65. This is another card that seems to be in demand, but not as rare as Blaze, for example.
As for the relatively large number of cards, such as Jetflow or Flexedge, which number 24 and 25 respectively, and are priced at just $5, these are easy to find and may have less of an impact on gameplay than the cards above.
My monitoring of the market and observation of these numbers helps me understand which cards will be popular with players and which are rare and difficult to find. This is very important, whether for buying a card to invest in or preparing my lineup for a race or challenge.
Honestly, The fun of Moon Karts isn't just in the racing but also in managing the cards and understanding the market. Every time I open the market and I feel like I'm on a new adventure, searching for treasure among the cards.
