Each Set Booster contains 12 Magic cards, 1 Art Card, and 1 token/ad card, Helper card, or card from The List (a special card from Magic's historyfound in 25% of packs)
It's worth noting that, when you put the three lore counters on copies you make with Esper Terra's first three chapters, you'll also trigger the first three chapters all at the same time
It's the perfect land for this set, though, as it's filled with a lot of creature types that any type of deck from any format can easily build a tribal-themed deck, and Cavern of Souls easily makes it much easier to do
Cards Realm has a virtual booster opening simulator for Conspiracy with realistic, rarity-weighted pulls
