# Card Supply

The number of cards in **circulation** can be found in a few locations, most obviously on the specific unit/summoner’s **CARDS** page.

This number represents the *total number of the selected cards* in circulation. If new copies of a card are currently being found via Booster Packs or Reward draws, then the *circulation* will increase per new card found. Whenever copies of a card are [combined ](https://docs.splinterlands.com/cards/combining-cards)or [burned ](https://support.splinterlands.com/hc/en-us/articles/9187762729492-Burning-Cards)from the supply, the circulation goes down.

When [cards are combined](https://docs.splinterlands.com/cards/combining-cards) to level them up, ***many cards become 1 card**.* For example, if 20 individual Blackmoor Tricksters are combined, those 20 individuals (1 BCX each) are removed permanently from the supply, and a single Blackmoor Trickster (20 BCX) remains. So the net, in this case, is a loss of 19 Blackmoor Tricksters from circulation.

### Set Cards vs Reward Cards <a href="#set-cards-vs-reward-cards" id="set-cards-vs-reward-cards"></a>

When Booster Packs are opened, each card flipped has a unique chance of dropping a card from the current set based on universal rarity chances. This means that as long as some Booster Packs from each set have not yet been opened, the *exact* *maximum supply* of any specific card from that set cannot be determined, only estimated.

With older Reward cards, on the other hand, there was a finite number of each card that were issued. Therefore, the *print run* of each Reward edition card was able to be tracked based on what percentage has been printed. The *print status* of each Reward card is searchable with [THIS TOOL](https://kiokizz.github.io/Splinterlands/rewardCards.html), created by community member @kiokizz.

Current reward cards (Soulbound reward cards) do not have a set limit, though when another set of new cards is in planning, this may be specified.

Once a card is no longer printed, the circulation of that card will only go down, because the cards in circulation can only be transferred, combined, and burned.
