A card is considered to be on cooldown for 24 hours since its last use when another user (other than the current owner) recently utilized the card for play in either a ranked match, tournament, delegation, or brawl. Challenges and practice matches should not apply cooldowns to your cards. You can determine whether a card has an ongoing cooldown by going to the market or your collection and selecting a card on either of these pages.
If you see a highlighted clock icon , this means that the card has an ongoing timer. Hover over the icon to check how much longer the card should be on cooldown before another player may use this card in battle. If there is no cooldown present on the card, then the clock icon will not be highlighted, which means it is available to be played immediately.
Note: Cards cannot be listed on rental markets as long as a cooldown timer is present on those cards.
When viewing cards within the Peakmonsters market, you may occasionally see a clock icon next to some cards listed for sale when selecting a card to populate its listing results. You may hover over the icon to display the remaining amount of time that this card will be on cooldown before being playable if purchased at this time.
Cooldowns also used to be viewable from any user's collection page within the Peakmonsters website, though this has been disabled for the time being in order to prevent possible exploits as explained within the following update notes.
