Guilds of Ravnica contains 259 cards (111 commons, 80 uncommons, 53 rares, and 15 mythic rares), but there are only 254 functionally different cards since all gates have 2 common slots. Boosters may include randomly inserted premium versions of any card. The name of the set is rather similar to the Ravnica: City of Guilds, but Wizards of the Coast doesn't perceive this as a problem. The set features five of the bi-colored Ravnican guilds: Selesnya , Boros , Golgari , Izzet and Dimir. Watermarks are used to better identify the guilds. To get a guild watermark, the card has to be two-color, optimized with two colors or use the guild keyword.[7][8]
The 5 basic lands of this set are not included within the 259 cards, meaning that they won't appear in booster packs but only in the planeswalker decks and the Bundle. They're all autumnal versions of the Richard Wright basics from Ravnica: City of Guilds and are numbered from #260/259 to #264/259. Neither contained in boosters are the 8 additional planeswalker deck exclusive cards - numbered #265/259 to #272/259 - and the Buy-a-Box promo, which has the number #273/259. Each Guildgate is featured in two common slots, each with different art, much like Wastes in Oath of the Gatewatch.
