Dominaria United Collation

Dominaria United is a large set with 101 commons, 80 uncommons, 60 rares, 20 mythic rares, and four variations of each standard basic land. This is the normal size for a large set of this era.

Dominaria United was sold in 15 card draft booster packs (which contain an additional ad card). Draft booster boxes have 36 packs. Draft boosters in English are printed in the USA, Belgium, and Japan. Foil cards are included in draft booster packs with advertised odds of 1 : 45 cards.

US Pack Anatomy

The US printing uses sequential collation with simple two-run 101 common collation. Each pack contains exactly one (non-foil) legendary creature.

Packs are front-facing and have common-uncommon-rare ordering followed by a basic land and an ad card. There are 10 commons, 3 uncommons, and 1 rare. If there is a foil card, it will appear after the rare, displacing a common.

Each pack contains six cards from the A common run followed by four cards from the B run. Foils can displace a card from either run.

There are three uncommon runs. A and B each have 30 different cards. The remaining 20 cards are legendary creatures which appear in their own run. The first uncommon is always A, and the second is always B. In 3/4 of packs, the third uncommon is a legendary creature. In the other 1/4 of packs, the rare is a legendary creature and the third uncommon can be from either A or B (but not part of a sequence with the other A or B uncommmon).

Common Runs

The A common run consists of 60 different cards each appearing twice plus Vanquisher's Axe, the short-printed common. Other than Vanquisher's Axe, the cards appear in a repeating pattern of green, red, black, blue, white. The choice of first card is mostly arbitrary.

The B common run consists of 40 different cards each appearing three times plus Vanquisher's Axe, the short-printed common. The choice of first card is mostly arbitrary.

Belgian Pack Anatomy

The Belgian printing uses sequential collation with simple two-run 101 common collation. Each pack contains exactly one (non-foil) legendary creature.

Packs are front-facing and have common-uncommon-rare ordering followed by a basic land and an ad card. There are 10 commons, 3 uncommons, and 1 rare. If there is a foil card, it will appear after the rare, displacing a common.

There are three common runs. The A run has 30 distinct cards each appearing four times. The B run has 36 distinct card each appearing three times and the C run has 35 distinct cards also each appearing three times. The cards with showcase versions appear in the A run with one of the four copies being the showcase version.

There are two uncommon runs. The A run has the 60 non-legendary uncommons. The B run has the 20 legendary uncommons. Packs contain 2-3 A uncommons followed by 0-1 B uncommons. Assuming all uncommons are equally likely to appear, B uncommons should appear in 3/4 of packs. (This is plausible.) Packs with legendary rare creatures are exactly those packs that do not contain a B uncommon.

Common Runs

The A common run consists of 60 different cards each appearing twice plus Vanquisher's Axe, the short-printed common. Other than Vanquisher's Axe, the cards appear in a repeating pattern of black, white, red, green, blue. The choice of first card is mostly arbitrary.

The B common run consists of 40 different cards each appearing three times plus Vanquisher's Axe, the short-printed common. The choice of first card is mostly arbitrary.

Uncommon Runs

The A uncommon run consists of 60 different cards each appearing twice. The choice of first card is mostly arbitrary.

Japanese Pack Anatomy

The Japanese printing uses sequential collation probably with 112 card sheets (which is the usual for Japan). (Perhaps some 56 card sheets are also used.) Each pack contains exactly one (non-foil) legendary creature.

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

There are 3 non-double-faced common runs: A, B, and C. A contains 27 distinct cards, and B and C each contain 37 distinct cards. Each pack gets 2 to 3 cards from A followed by 3 to 4 cards from B and 3 to 4 cards from C. This means packs are either 2-4-4, 3-3-4, or 3-4-3. The exact ratios may depend on the way foil collation works.

Foils displace a common. Packs with foils obey the normal ranges for A, B, and C cards which means they are 2-3-4, 2-4-3, or 3-3-3.

There are two uncommon runs with legendary creatures and three uncommon runs with non-legendary cards. The first legendary run contains the non-showcase version of each of the 20 uncommon legendary creatures. Each of these appears twice. There is also one copy of the showcase version of the first 16 uncommon legendary creatures. (This accounts for 56 slots.) The remaining 4 showcase cards are in a different run. These cards are: Tura Kennerüd, Skyknight; Uurg, Spawn of Turg; Vohar, Vodalian Desecrator; and Zar Ojanen, Scion of Efrava. Between the uncommon cards and the rare, there will always be exactly one legendary creatures. To ensure uncommons have equal rarity, an uncommon legendary creature should appear 3/4 of the time (and the main legendary uncommon run should appear 7/10 of the time).

The first non-legendary uncommon run, run A, contains four non-legendary cards: Battlewing Mystic, Djinn of the Fountain, Relic of Legends, and Walking Bulwark. These cards never appear in packs with a legendary uncommon. A card from this run should appear 3/20 of the time. It is slightly plausible that these cards and the four extra legendary showcase uncommons share the same run, but I doubt this somewhat because the special collation of legendary creatures must distinguish between legendary and non-legendary uncommons which is probably easier if they are in different hoppers. (The rest of the uncommon structure also distinguishes them.) (The as-fan of these cards is too low for me to easily confirm the structure of these runs, especially as there are not many distinct cards here.) The B and C non-legendary uncommon runs each has 28 distinct cards. Packs with a legendary creature from the main run have either 1 B followed by 1 C, or 2 B cards. Packs with an overflow showcase legendary always have 2 B cards. An A uncommon is always followed by 2 C cards. The remaining packs (which should account for 1/10 overall) have either 2 B followed by a C or a B followed by 2 C. It is plausible that these are equally likely (though the sample size is small); this would make it so that packs with a legendary creature from the main run should have 2 B cards 1/7 of the time (also plausible).

Common Runs

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

Uncommon Runs

The main legendary uncommon run contains two normal copies of each of the 20 uncommon legendary creatures. For the (alphabetically) first 16 of these, there is also one copy of the showcase version. (The excluded showcase cards are: Tura Kennerüd, Skyknight; Uurg, Spawn of Turg; Vohar, Vodalian Desecrator; and Zar Ojanen, Scion of Efrava. These cards appear in a different run.) The choice of first card is mostly arbitrary.

The B uncommon run consists of 28 different cards each appearing four times. The choice of first card is mostly arbitrary.

The C uncommon run consists of 28 different cards each appearing four times. 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 both faces. Some tokens with the Dominaria United Commander set code and expansion system are included. These cards have unified numbering out of 26. The cards are printed in a 112 card run with items appearing different numbers of times.
