Kaladesh contains 264 cards (15 basic lands, 101 commons, 80 uncommons, 53 rares, 15 mythic rares) and includes randomly inserted premium versions of all cards. The expansion symbol is a Far Eastern inspired floral motif, representing the aether of the plane. Kaladesh premieres Planeswalker decks, which replace Intro packs. These contain 10 additional cards that are considered to be part of the set (2 mythic planeswalkers, 2 rares, 2 uncommons, 2 commons and 2 common dual lands). These are numbered #265/264 to #274/264). The Fat pack for this set was reimagined as the Kaladesh Bundle.
Although Wizards of the Coast used the ligature Æ — the A and E combined into one letter — for aether since the beginning of the game, this was changed for Kaladesh, which features the stuff heavily. According to Blake Rasmussen, it caused way more issues than it was worth (particularly in translation). The set introduces create as a new vocabulary word. Create is used when a card or effect puts a token onto the battlefield.
Each Kaladesh Booster Box contains 36 packs of 15 cards each. Premium foil cards are randomly inserted.
