# Cards level up

* Each card can be upgraded a certain amount of times.<br>
* &#x20;Upgrading increases the effect of cards and sometimes even adds a new one. <br>
* To upgrade a card a player needs: \
  \- SC; \
  \- card currency (non-crypto - is acquired by finding duplicates of cards in boosters). <br>
* The price of the upgrade depends on: \
  \- the current level of the card - higher level = higher price; \
  \- the rarity of the card - higher rarity = higher price.
