A Set is a group of thematically and mechanically cohesive group of cards released over one or more expansions.


An Expansion is all the cards, champions, cosmetics, and game modes released with a major patch (roughly every two months). Each expansion will have a unique name.

A set shares its name with the first expansion in it. All cards from expansions of the same set will all be part of that set. It has been implied that this will be pertinent for future deckbuilding rules for different formats and game modes.[1]

A new Ranked season starts whenever a new expansion is released.

The Foundations (cards in the game initially) and Rising Tides (the first new cards) Set releases occurred before this conception of Expansions existed. See Exceptions.

Variety Set[]

  • Variety Sets are minor expansions released in between major expansions for the game. They occur once every 3 months and feature 1 to 2 new cards for most regions. They are aimed at supporting existing archetypes and do not feature any new champions or mechanics.

Champion Expansion[]

  • A champion expansion was first introduced in V2.1. Champion expansion are smaller than normal expansions, usually include a collection of cards directly related to the champions included in the expansion.
    • Aphelios.
    • Viego & Akshan.
    • The Path of Champions

Current rules[]

  • A set will have three expansions. Expansions are generally released every two months.
  • A set will focus on a new region.
  • The first expansion in a set will be larger, containing the new region's major themes.
  • Second and third expansions each will be half of the first expansion size. These will have a mix of new themes, new mechanics, evolutions of strategies from the first expansion.
  • A set will add a new champion to each region.
  • An expansion will contain new cards for each region. However, an expansion may release unequal number of cards to the regions, including the number of champions.
  • After a set is fully released and completed, all regions will have an equal number of champions and near-equal share of other cards.


  • Some Ranked seasons do not share their name with their Expansion;
    • The Beta Season, the first season that started while only the Foundations set was in the game,
    • Season of Plunder and Season of Fortune, which both occurred between the release of Rising Tides and Call of the Mountain, due to the current conception of Expansions not yet existing.
  • It was four months between the Rising Tides and Call of the Mountain expansions.
