Gucardprices created this analysis of card types and prices that i think is very valuable to people trading or even just looking to purchase cards for their decks. It appears that Epic and Legendary cards with less shine are the cards people are looking for most. People may not yet see the value in buying Gold or Diamond cards until they are sure of which cards will maintain their value over time.

One of the things I find very interesting about this game is that it may be one of the first crypto asset games that has enough adoption and enough liquidity of the assets to allow the markets to function properly.
In comparison a card game like MTG has huge adoption but there is a lot of friction when buying and selling. You may have to travel to a store or else get them delivered, adding cost of the travel or shipping. Also, there are many more marketplaces where these cards are available causing poor liquidity in many of these markets, which can affect card values.
I love seeing all the content that websites and posters are creating for this game. These things make the community much more exciting to be part of.
