Foundations Set Cube (4:2:1:1)
-FDN play booster rarity ratio
7.37C : 4.214UC : 1.215R : 0.201M : 1L
(with 80C, 101UC, 60R, 20M, 10L)
-Rarity ratio in this cube
4C : 2UC : 1R : 1M
-Rate of rare+mythic is about 1.7 times more than play booster for pure random draft
-12 copies of Hare Apparent
-10 basic land included for L sort control purpose (If you want to control L sort in each pack only, there will be max. 46 packs available, however please note that there are not enough commons to follow official rarity ratio in this case)
-Special Guests are not on list, the drop rate is too low (1.5% at 7th C sort), but I would practically insert an 'Invitation' card inside the draft and make an extra draft among 10 SPG instead of putting all of it into the draft.
Controlled sealed (Maximum 6 deck card pools supported)
This is the best way to emulate play booster prerelease, with the most average distribution to provide a relatively fair play.
By rarity pile, distribute 44C, 25UC, 8R, 1M, 6L for each deck card pools.
Controlled draft (4 to 12 players)
This is the best way to emulate play booster draft , with the most average distribution to provide a relatively fair play.
Cube shells are recommended in order to randomly distribute rarity modified packs to players.
By rarity pile, distribute the following 12 packs:
2 packs of 7C, 4UC, 1R, 1M, 1L
3 packs of 7C, 4UC, 2R, 0M, 1L
3 packs of 7C, 5UC, 1R, 0M, 1L
4 packs of 8C, 4UC, 1R, 0M, 1L
For 8 to 12 players draft, double/triple each type of packs.
