The cosmic deck (simply called the deck in card texts) is the main deck of cards used in playing Cosmic Encounter. When cards are drawn (including for players' starting hands), they are drawn from this deck unless otherwise specified. Defensive allies' rewards are drawn from this deck if the reward deck is not in use.
If playing with 7 or more players, the large group deck must be shuffled with the cosmic deck in order to play.
In the current edition, the cosmic deck includes 72 cards:
- 55 encounter cards:
- 6 reinforcements with values , , and
- 11 artifacts:
Flare cards dealt during setup are also mixed into the cosmic deck.
Cosmic Quake Edit
A cosmic quake occurs if there are no cards remaining in the cosmic deck or discard pile and a player attempts to draw one or more cards from the cosmic deck. When this happens, all players must discard all the cards in their hands, then the discard pile is shuffled to reform the cosmic deck and each player is dealt a new hand of eight cards.
No other decks besides the cosmic deck cause a cosmic quake; they simply run out and no more cards can be drawn from them.
This rule was added in Cosmic Incursion.
