divide the cards in 40 piles ('boosters') of 11 cards with the following division between rarity

1 mythic or rare
3 uncommons
5 commons
1 mythic/rare/uncommon contraption
1 common contraption

Ways to play:
- sealed, 2-7 players, give every player 6 boosters
draft
- boosterburn draft, 2-11 players every one gets to pick one from each booster, then the remaining cards are put back in the box. Leaves you with 40 cards,
- normal draft, but with 4 boosters
- glimpse draft, double the amount of boosters per person, each time you get passed a booster pick one card and burn one, for each second booster, first burn one and pass the booster without picking one
