I want to buy a booster box to hold some office drafts.
I remember booster packs as having 15 cards per pack, which is in line with what Wikipedia says:
Starting with the Shards of Alara block, booster packs for both Core Sets and Expansions began to contain 1 land, 10 commons, 3 uncommons, either 1 rare (7/8 chance) or 1 mythic rare (1/8 chance)
But the Amazon page for the Core M12 Sealed Booster Box says that there are "10 Cards/Pack".
Did something change, or is the Amazon page wrong?
