Mirror

"Mirrors your last card played for +1 Elixir"

Summary

 * The Mirror is unlockable from the Spell Valley (Arena 5).
 * The level of the copied card depends of the level of the Mirror.
 * When in-game, the card will display your last placed card inside the Mirror.
 * This does not apply if you have not deployed a troop yet, instead it will display a question mark.

Strategy

 * The Mirror makes the player able to repeat a powerful card, such as the Goblin Barrel, leaving the opponent without Elixir to counter it.
 * Elixir Collectors can be mirrored in order to boost the players Elixir production, allowing them to deploy cards faster.
 * But it will give you only a profit of 1 Elixir.

Trivia

 * On 2/2/16, the February Update increased its level of mirrored common cards by 4 and mirrored rare cards by 2.
 * On 23/3/16, a Balance Update decreased the mirrored Legendary cards level by 1.
 * The Mirror is the only card that doesn't have a defined Elixir cost.
 * Because of this, the Mirror doesn't effect the average elixir cost of the player's Battle Deck.
