Best of 1, 3 rounds, 4 pack draft.

Booster Draft is a format in which each player receives four sealed Altered booster packs. Players open packs, select cards from the packs opened, pass the pack and repeat until all cards are drafted. Then players build a deck of at least 30 cards from the pool of cards they selected.​

• A deck must contain a minimum of 30 cards.
  
  • Token cards do not count towards the deck minimum. If you have token
    cards to go with your deck, they start outside of your deck.
    
• You may play cards from up to three different factions.
  
• A deck can include a Hero card. If so, it counts toward the 30 cards minimum.
  
  • Your Hero must be from one of the factions in your deck.
    
  • You may choose to not play a Hero card.
    
• There are no restrictions on the number of cards with the same name that you can play in your deck.
  
• There are no restrictions on the number or rare or unique cards you can play in your deck.
• Mana Convergence tokens act as any card in your deck, but:
  
  
  • They can not be played in any other zone than the mana zone by their owner.
    
    • They cannot be played in an Expedition, Reserve or Landmark area
      
  • They can be affected by card effects such as “Discard a card to do
    X” or “Your opponent discards a card” and are counted as a card for any
    other purpose like “I gain X boosts based on the number of cards in your
    discard pile”.
