Crystals

Earn Chests to obtain Gold, Gems, and Cards. Chests won from battles must be unlocked before you can receive their contents. Unlocking a chest takes a certain amount of time. Alternatively, the wait can be skipped using some Gems, or hastened using boosters from the Shop. Each player has four chest slots, so you can only have up to four chests waiting at a time. It is still possible to battle when your chest slots are full, but no chests will be won, only Gold and Crowns. Chests always contain cards from the Arena the player earned them in and below and/or cards the player has already unlocked, except for Legendary Chests, which can contain a Legendary Card from any Arena. Unlocking a new Arena (apart from the Legendary Arena) adds new Cards to the Chest rewards — none are taken out.

 * The Lightning Chest and the Mega Lightning Chest allow you to replace card stacks of your choice, the number of "Strikes" depending on Arena.
