# Cards

*Note: Concepts contained in this whitepaper are subject to change.*

Cards are at the heart of this game. Player and coach cards will be available as NFTs and sold in packs. Equipment and skill cards will be earnable as rewards through gameplay. The attributes of each of the cards are described in the following sections.

Each of these cards can be **combined** with duplicates and gain **experience points (XP) to achieve higher levels**.

* **XP Level:** Users can advance in card XP level by playing their cards in matches.
* **Star Level:** Users can advance in card star level by combining “like” cards. This unlocks new skill and equipment slots on each card.
* **Unlocking Slots:** Combining cards will unlock new slots for equipment and skills.<br>

There are two foil types for player cards and coach cards:

* **Non-foil:** The base level coach card is a non-foil card.
* **Gold foil:** These cards will be some of the rarest in the game.
