(From 1997--2008, Wizards of the Coast also used the term "cycle" when describing the associated storyline .) Blocks were cohesive products: they centered around one plane, followed a particular storyline, and contained cards and mechanics that supported both . Blocks generally consisted of one large "stand - alone" expansion set of 250--300 cards, followed by one or two small expansion sets of 150--200 cards which continue the themes introduced in the large set . Like the base set, stand - alone expansion sets contain basic land cards; other expansion sets do not . Beginning with Alliances, expansion sets were given codenames while in development; the code names of the expansions of a cycle usually fit together to form a phrase or common theme . Starting with Mirage in 1996, blocks were officially refined in form: they would consist of would be three sets, large - small - small . With Zendikar block in 2009, the traditional large - small - small block structure began to be varied, with some blocks including a second large set later in the block . Starting with the Battle for Zendikar block in 2015, the default structure of a block was changed to large - small, with each block consisting of only two sets and two blocks released per year . </P>

When does the next magic expansion come out
