Draft/Deckbuilding:
Draft 3-card commander boosters until second pick, put the third card back into the pool, then every player gets 1 commander at random from the pool.
Draft four 15-card boosters.
Build a 50 card deck and choose a legal commander from your 3 options. (51 cards total)
All cards must be in your commander's colour identity. (Exception: If Chronomaton is your commander, you may play any number of Plains, Island, Swamp, Mountain and Forest.)

Games:
Two 4-player pods, 30 life, 16 commander damage is lethal
The players who don't go last do not draw a card during their first draw step. The player who goes second scries 1 after mulligans, the player who goes third scries 2 after mulligans.
The winners of the respective pods play each other in the finals.
