On April 2, 2020, Intelligent Systems announced that Cipher would be ending with the twenty-second expansion releasing in late 2020.
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.
Like in the series, there is the concept of a leveling a character, and is done so through "level up" or "Class Change" by stacking cards with the same name on top of a character you control and paying the cost. Said costs come in the forms of bonds, which are set aside from the field and placed in the "bond area", and also act as a separate system for using skills.
