Fire Emblem 0: Flame, Steel, Thought and Grief Expansion

In Fire Emblem 0 (Cipher), two players go in a turn-based battle between their Main Characters that are set aside from the Deck. By selecting one card that meets the conditions at the start of the game from within the deck built with at least 50 cards (with no upper limit of cards you may have, save for having more than 4 copies of the same card), they each attempt to defeat the opponent's main character by destroying one of the five "Orbs" serving as their life, and winning when there aren't any more orbs.

Each Series contains 100 different types of cards, with rarities for each card spanning from Normal (N), High Normal (HN), Rare (R) and Super Rare (SR). There is also the guaranteed R+ in each box and the off chance of having an SR+ instead. Prior to Booster Set 5, R+ and SR+ have a metallic gold or silver border around the edge, and some have a special foil signature of the character's voice actor. Starting from Set 5, they also have alternate arts for each card.

The thirteenth series features characters from The Blazing Blade, Shadow Dragon, and Heroes.
