Tribal Wars

Tribal Wars is a casual constructed Magic: The Gathering format that emphasizes creature combat and tribal themes: one-third of every deck must be of a single creature type.

Rules
Because Tribal Wars is a Constructed format, each deck must contain at least 60 cards, and players may build decks using Standard, Modern, Legacy or Vintage deckbuilding rules. The format provides players the opportunity to do battle with their favorite Magic creatures to see which tribe is the game's most powerful!
