- This article is about the Conspiracy set. For the format, see Conspiracy (format). For the card type, see Conspiracy (card type).
Conspiracy contains 210 cards (80 Commons, 60 Uncommons, 35 Rares, 10 Mythic Rares and 25 cards in the land slot ); 65 are new cards with new mechanics that enhance multiplayer play. Returning favorites from throughout Magic 's history round out the set and cultivate an environment of deception and treachery. The Conspiracy set is designed to be drafted with six to eight players who then split into groups of three or four players for free-for-all multiplayer games.  The expansion symbol is a seal on a scroll.
Each Conspiracy pack has one "draft matters" card which is in the pack in lieu of a basic land.
Conspiracy will not be released on Magic Online, but certain cards from the set will be made available in Vintage Masters. There are sixty-five new cards in Conspiracy. Fifty-two of the new cards are legal in Legacy and Vintage; thirteen cards with the new Conspiracy card type are not.  These 13 Conspiracies and 12 draft affecting cards take the place of the normal basic land in a booster. The set features an all new planeswalker card for Dack Fayden. 
A preview card (Magister of Worth) was hidden in a Born of the Gods prerelease pack, which had a serial number printed on it, itself leading to a voice message that turned out to be a cipher for another card's information (Cogwork Librarian).  The official announcement was made on February 13 and was also ciphered,  with a version in clear posted the next day. 
During Pro Tour Journey Into Nyx, WOTC released a marketing video showing a draft session of conspiracy. It was hosted and all rules were explained by Graham Stark, while the draft was set up with eight players: Kathleen De Vere, Marshall Sutcliffe, Brian David-Marshall, pro player David Williams, former NFL player Chris Kluwe, Nathan Holt, Kenji Egashira, and level 5 Judge Toby Elliot. Previously several short and humorous videos showing Graham inviting the players were broadcast.

Themes and mechanics
The set introduces ability words Will of the council and Parley.  Will of the Council allows the effect of cards to be decided by popular vote, with other cards giving players the ability to vote multiple times. Parley on the other hand has each player reveal the top card of his or her library, then draw that card, with an additional effect for the player who used the Parley card that scales based on the number of nonland cards revealed this way. A new keyword called Dethrone is also in the set, giving creatures additional +1/+1 counters if they attack the player with the highest life total. 
Conspiracy also includes a number of artifact creatures that affect the draft itself. These cards are drafted face-up, and can be used for a later effect such as for example putting them back into a booster to pick an additional card from that booster.
The set further introduces the new Conspiracy card type. These cards are of normal size with a regular card back, but can not be played in a deck as they have no casting cost. Instead these cards are placed in the Command zone at the beginning of the game and have their effects there. Some of these cards have the keyword Hidden agenda, which means they start the game face-down with something noted down for them. They can be turned face-up at any time so their effects become known to the entire table and can take place.
