  %em Canadian Highlander
  is an unofficial competitive non-rotating Singleton Constructed format. It uses 100-card decks without commanders.

%p
  Canadian Highlander's most distinctive feature is the points list, which allows the restriction of powerful cards in a singleton format without resorting to power-level bans. A deck can have up to 10 points. Lore Seeker automatically updates to the newest points list at least once per week.
