Crimson Vow is a large set with 100 commons (10 of which are double-faced), 83 uncommons (23 of which are double-faced), 64 rares (11 of which are double-faced), 20 mythic rares (5 of which are double-faced), and two variations of each standard basic land. These numbers are the same as the previous set, Midnight Hunt. Foil cards are included in booster packs with advertised rate of 33% of boosters. The set was printed in English in the USA, Belgium, and Japan.

Crimson Vow was sold in 15 card draft booster packs (which contain an additional ad card and double-faced card placeholder). Draft booster boxes have 36 packs.

The US printing uses sequential collation with non-standard common collation to account for the double-faced cards. (However, the collation scheme is different that the scheme used for Midnight Hunt.)

Packs are front-facing and have common-uncommon-rare ordering followed by a basic land, an ad card, and a placeholder card. There are 10 commons, 3 uncommons, and 1 rare. If there is a foil, it will displace a common and appear after the basic land. The last common is always double-faced. (This will not be replaced by a foil.) Additionally, there will be either one double-faced uncommon or the rare will be double-faced.

10 Commons | 3 Uncommons | 1 Rare | 1 Land | 1 Ad Card | 1 Placeholder Card | |

9 Commons | 3 Uncommons | 1 Rare | 1 Land | 1 Foil | 1 Ad Card | 1 Placeholder Card |

There are three non-double-faced common runs. The A run contains 40 distinct cards each appearing three times, the B run contains 30 distinct cards each appearing four times, and the C run has 20 distinct cards each appearing six times. The commons with showcase versions appear in A and C with one third of the copies being the showcase version. The vast majority of packs contain have 4 A cards followed by 3 B and 2 C. There are also a small number of packs with 4 B cards which can appear alongside either 3 A cards or 1 C card. From the perspective of balancing the commons, such packs are only acceptable is B cards are more likely to be displaced by foils, and this does seem to be the case, although cards from any of the runs can be displaced by a foil. No packs with 4 B cards also contain a foil. (So, perhaps an equivalent formulation is that foils always displace B cards and packs that have 3 A or 1 C card with a foil are 4 B packs where the fourth B card has been displaced.)

Each pack has an additional double-faced common after the other commons. Because the double-faced common is never displaced, double-faced commons should be slightly more common that non-double-faced commons.

There are two non-double-faced uncommon runs. The A run contains 40 distinct cards each appearing three times. The B run contains 20 distinct cards. Packs contains 1-2 A uncommons followed by 0-2 B uncommons totalling 2-3 cards. (So, 0+1 and 2+2 are not possible, but other combinations are.) In cases where there are only two such cards, there will be a double-faced uncommon. (There rare will be double-faced exactly when the third uncommon is not.)

Mathematically, to ensure all uncommons are equally uncommon, a double-faced uncommon should appear 69/83 of the time. This number is plausible, but I doubt it. The rare should be double-faced 27/148 of the time (as in Zendikar Rising) to ensure all rares are equally likely, and this number is close to the 14/83 given by uncommon math. (In fact, it is much closer than if there were 20 double-faced uncommons as in Zendikar Rising.)

The A common run consists of 40 different cards each appearing three times. The cards are white, blue, and red. For cards with showcase versions, one of the three copies is the showcase version. The choice of first card is mostly arbitrary.

The B common run consists of 30 different cards each appearing four times. The cards are green and black. The choice of first card is mostly arbitrary.

The A common run consists of 20 different cards each appearing six times. For cards with showcase versions, two of the six copies are the showcase version. The choice of first card is mostly arbitrary.
