Cooldown

Cooldown is the number that is displayed in the top left-hand corner of your card. This signifies the amount of turns that must pass in order to play this card. During your Wait Phase, the cooldown of all cards in your Hand is decreased by 1. For example, if you have a card that has 3 Cooldown, you must wait 2 turns (from initially drawing it or adding it to your hand) before you are able to play said card. There are Skills that decrease the Cooldown of certain cards in your hand, so make sure to use them to get out higher Cooldown cards faster.
