You can rest now, Golos, Tireless Pilgrim.

One of Magic: The Gathering’s most popular cards — Golos, Tireless Pilgrim — has been banned from play in the widely played Commander format, according to an update from the Commander Rules Committee, an independent group that both created the format and oversees the official rules for play.

Rules Committee founding member Sheldon Menery announced the Golos ban in an update posted Monday.

Menery acknowledged that Golos is “both popular to play with and unpopular to play against,” and that the card’s “presence crushes the kind of diversity in commander choice which we want to promote.” In the same announcement, the rules committee unbanned another card, Worldfire.

Menery added that the committee doesn’t expect Magic: The Gathering publisher Wizards of the Coast to print cards similarly powerful to Golos, Tireless Pilgrim in the near future, “so a surgical strike now makes sense.”.

What sets the format apart is that one of those 100 cards must be a Legendary Creature, a type of creature first introduced to the game in 1994.
