Cards

General Information

 * Cards are the only method of deploying troops, spells, and buildings onto the battlefield.
 * Spells can be cast anywhere in the battlefield, whilst buildings and troops must be spawned on your territory.
 * Deploying cards costs Elixir, gradually gained during battle.
 * Cards can be obtained by buying them with Gold or finding them in assorted Chests.
 * Chests can always contain cards from Arenas that you have already passed.
 * Unlocking a new arena adds new cards to the Chest rewards- none are taken out.
 * If you received Chests in a lower Arena, it will only contain cards from that arena and below, even if you advance to a higher arena.
 * Duplicate cards obtained will fill up an upgrade meter.
 * Once the meter is full, you can upgrade the card with Gold.
 * If your card reached the max level, you can hold additional cards (100 for Commons, 10 for Rares and 1 for Epic) for donations.
 * When even this meter is maxed out, each card recived will give you a certain amount of Gold.
 * For cards, all health and damage stats are increased by +10% per level.
 * There are 4 levels of rarity of cards: Common (signified by gray or pale blue), Rare (signified by orange), Epic (signified by purple) and Legendary (signified by a color rainbow).
 * There are currently 48 cards available.
