# Cards and decks

> Power-up cards, energy and building your deck.

Once you have a deck, you bring power-up cards into your fights, including **In-Game Cards** PvP matches.

## In a match

* Your deck starts with three slots, and all six open after Star Gym. With a full deck you hold four active cards and two in reserve.
* Playing a card costs energy, which recharges during the match.
* Drag a card onto **TO YOU** or **TO OPPONENT**. On the web you can also press `1` to `4`.
* When you play a card, a reserve card takes its place.

## The cards

| Card          | What it does                                                                 |
| ------------- | ---------------------------------------------------------------------------- |
| Leverage      | Your next close deals, or takes, extra damage.                               |
| Margin Call   | Reveals your opponent's active hand for a few seconds.                       |
| Shill         | Your winning closes hit harder for a few seconds.                            |
| Diamond Hands | Caps the next big incoming hit within a short window.                        |
| Rug Pull      | Steals health from your opponent and heals you by the same amount.           |
| HODL          | Hold a position long enough and you restore health.                          |
| Hack          | Deals direct damage to your opponent.                                        |
| Airdrop       | Restores some of your health.                                                |
| Borrow        | Costs you a little health now; if your next close wins, it hits much harder. |

Each card shows its exact effect in the game.

## Building your deck

* Beat Recon on the [solo road](/play/solo) to claim the free **Genesis Deck**.
* After Star Gym, the Store's **Booster Pack** adds Hack, Airdrop and Borrow.
* Levelling a card up costs [gold](/progress/gems-and-gold) and needs a minimum player level.

Beating Bun earns **Encore**, a trophy card that stays in your collection. It can't go in a deck.
