Innistrad: Midnight Hunt Collation

Midnight Hunt 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. The non-double-faced counts are similar to earlier large sets, and the double-faced cards are similar to Zendikar Rising (although that set didn't have double-faced commons). 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.

Midnight Hunt 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.

US Pack Anatomy

The US printing uses sequential collation with non-standard common collation to account for the double-faced cards.

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.

There are two non-double-faced common runs. The A run contains 58 distinct cards each appearing twice. The B run contains 32 cards each appearing three times. The commons with showcase versions appear in run B with one of the three copies being the showcase version. Packs contain 5-6 A commons followed by 3-4 B commons. If there is a foil, these ranges are still true (so foil packs have 5 A commons and 3 B commons). Thus, among non-foil packs, 6 A packs are much more likely. Mathematically, they should appear 79/90 of the time for non-foil packs (based on the assumption that commons from these runs are equally likely).

Each pack has an additional double-faced common after the other commons. There is one common double-faced run with each card three times. For cards with showcase versions, one of the three copies is the showcase version.

There are two non-double-faced uncommon runs. The A run contains 27 distinct cards each appearing four times. The B run contains 33 cards each appearing three times. The uncommons with showcase versions appear in run B with one of the three copies being the showcase version. Packs contains 0-1 A uncommons followed by 1-2 B uncommons totalling 2-3 cards. (So, 0+1 is 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.)

The double-faced uncommons also have two runs. There is a run that contains 12 cards each repeated three times. All the showcase cards appear in this run, and, for those cards, one of the three copies is the showcase version. The other run has 11 cards. (I'm not sure of the repetition count.)

Mathematically, to ensure all uncommons are equally uncommon, a double-faced uncommon should appear 69/83 of the time, and 0 A packs will only appear 2/83 of the time (not conditioning on the double-faced slot). These numbers are plausible, but I doubt them. 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.)

Common Runs

The A common run consists of 58 different cards each appearing twice. The cards are mostly blue, black, and green. The choice of first card is mostly arbitrary.

The B common run consists of 32 different cards each appearing three times. The cards are mostly red and white. For cards with showcase versions, one of the three copies is the showcase version. The choice of first card is mostly arbitrary.

The double-faced common run consists of 10 different cards each appear three times. For cards with showcase versions, one of the three copies is the showcase version. The choice of first card is mostly arbitrary.

Uncommon Runs

The A uncommon run consists of 27 different cards each appearing four times. The choice of first card is mostly arbitrary.

The B uncommon run consists of 33 different cards each appearing three times. For cards with showcase versions, one of the three copies is the showcase version. The choice of first card is mostly arbitrary.

The first double-faced uncommon run consists of 12 different cards each appearing three times. For cards with showcase versions, one of the three copies is the showcase version. The choice of first card is mostly arbitrary.

Token Run

Most of the marketing cards in this set have a token or emblem on the front face. In addition, there is a card that has an advertisement for MTG Arena on the front face. They are printed in a 121 card run with items appearing different numbers of times.

Belgian Pack Anatomy

The Belgian printing uses sequential collation with non-standard common collation to account for the double-faced cards.

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.

There are three non-double-faced common runs. The A run has 20 cards each appearing six times, the B run has 30 cards each appearing four times, and the C run has 40 cards each appearing three times. Each pack contains two cards from A followed by three from B and four from C. A foil can displace a common of any run. Showcase commons appear in run A. For cards with a showcase version, two of the six copies are the showcase version.

Common Runs

The A common run consists of 20 different cards each appearing six times. For cards that have a showcase variants, two of the six copies are the showcase variant. The choice of first card is mostly arbitrary.

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

The C common run consists of 40 different cards each appearing three times. The choice of first card is mostly arbitrary.

Japanese Pack Anatomy

The Japanese printing uses sequential collation with 112 card sheets (which is the usual for Japan). Probably the sheets are 14 × 8.

Packs are front-facing starting with the placeholder card, the ad card and a basic land, then the rare, 3 uncommons, and 10 commons. If there is a foil, it will appear before the basic land, displacing a common.

There are 3 non-double-faced common runs: A, B, and C. A contains 16 distinct cards, and B and C each contain 37 distinct cards. Each pack gets 1 to 2 cards from A followed by 3 to 4 cards from B and 3 to 4 cards from C. This means packs are either 1-4-4, 2-3-4, or 2-4-3. The exact ratios may depend on the way foil collation works.

Commons with a showcase version appear in the C run. The C run has three copies of each card, and when there is a showcase version, one of the three copies is the showcase version.

Foils displace a common. As far as I've seen, there will still be at least one A common, three B commons, and three C commons. I haven't seen foil packs with two A cards, but the other two combinations are possible.

Common Runs

The A common run consists of 16 different cards each appearing seven times. The choice of first card is mostly arbitrary.

The B common run consists of 37 different cards each appearing three times. The choice of first card is mostly arbitrary.

The C common run consists of 37 different cards each appearing three times. For cards with a showcase version, one of the three copies is the showcase version. The choice of first card is mostly arbitrary.
