What is Highlander?

Highlander (or German Highlander, or European Highlander) is a 100 cards singleton format that is mostly played around Europe. The deck building rules are quite simple: Each deck must contain at least 100 cards that are not on the Banned List. Only basic lands and cards that abolish the usual limitation, like Shadowborn Apostle, can only be contained once in the deck. In addition to these limitations on deck building, there is also and there is no sideboard.

The Mulligan

For a long time, Highlander players had access to more powerful mulligans than other (official) formats. However, currently we are using the London Mulligan, where

103.4. [e]ach player draws a number of cards equal to their starting hand size, which is normally seven. (Some effects can modify a player's starting hand size.) A player who is dissatisfied with their initial hand may take a mulligan. First, the starting player declares whether they will take a mulligan. Then each other player in turn order does the same. Once each player has made a declaration, all players who decided to take mulligans do so at the same time. To take a mulligan, a player shuffles the cards in their hand back into their library, draws a new hand of cards equal to their starting hand size, then puts a number of those cards equal to the number of times that player has taken a mulligan on the bottom of their library in any order. Once a player chooses not to take a mulligan, the remaining cards become that player's opening hand, and that player may not take any further mulligans. This process is then repeated until no player takes a mulligan. A player can take mulligans until their opening hand would be zero cards.

New Editions

New cards that are printed in upcoming sets are legal in Highlander starting with their release (not pre-release).
