View the expected number of cards per player, per draft format. Standard Draft assumes 3 packs of 15 cards.We use 'Asfan' to mean the expected number of cards per player opened. So if red creatures have an Asfan of 2, on average I will see 2 red creatures in all the packs I open together. The more common meaning is per pack instead of per player, but with custom formats it makes more sense to talk about per player.
