Magic: the Gathering Booster Draft

Booster draft is a limited Magic the Gathering format of which players will build
their 40 card deck from a pool of 3 draft booster packs. Each player will open
one pack at a time, select a card from it and pass it to the player next to them.
After passing all cards from 3 booster packs they will have a set amount of time
to build a deck (typically 50 minutes). Players then compete over 3 rounds of
Magic the Gathering games with each match win scoring the player one pack
as prize. Additional prizes will be given out at the event as well.
