Open these packs in order:
From every booster, draft one card, and pass the rest to the next player, until all cards have been drafted. Direction changes with every booster.
Some cards are drafted face up, or ask you to reveal them and note something as you draft them, and cards in the game care about what happened.
From cards you draft and any number of basic land cards, build a 40 card deck. Conspiracy cards are never part of your deck - as the game begins you may put any number of the ones you drafted into the command zone instead, face down if they have hidden agenda.
Games are played as free-for-all multiplayer, and you can attack multiple players. See rule 905 for the full rules.
Drafting is not supported on this website.
