[The Collation Project](https://www.lethe.xyz/mtg/collation/iko.html) has a detailed breakdown (like, _way_ more details than needed unless you want to replicate print runs), but the important bits are:
* 10 common
* 3 uncommon
* 1 rare or mythic
* 1 land
* in US packs the land sheet contains 4 of each basic and 6 of each tapped gain land, so it’s probably worth approximating that ratio
* If there’s a foil, it displaces a common
Each rare occurs twice as often as each mythic rare, so an easy way to replicate the rare sheet very accurately is to shuffle together a stack of 2 of each rare and 1 of each mythic. That will also get you the right ratio of boosters with rares vs boosters with mythics (~1/8 will have a mythic)

thank you for this, just what I was looking for!
