Scars of Mirrodin Collation

Scars of Mirrodin is a large set with 101 commons, 60 uncommons, 53 rares, 15 mythic rares, and four variations of each standard basic land. This is the normal size for a large set of this era. Foil cards are included in booster packs with advertised odds of 1 : 67 cards. The set was printed in English in the USA and Belgium.

Scars of Mirrodin was sold in 15 card booster packs (which contain an additional ad card). Booster boxes have 36 packs.

US Pack Anatomy

The US printing uses sequential collation with C1/C2 common collation.

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

10 Commons	3 Uncommons	1 Rare	1 Land	1 Ad Card
9 Commons	3 Uncommons	1 Rare	1 Land	1 Ad Card	1 Foil

Packs are evenly split between C1 commons and C2 commons. C1 packs have 3 A cards, 1-2 B, and 5-6 C. C2 packs have 3-4 A cards, 1-4 B, and 2-6 C.

When a foil appears in a pack, it will displace a common card. Uncommon foils displace A commons. Rare foils displace C1 commons. Common foils can't be fully understood as displacing a common from a particular run. The great majority of common foils appear in C2 packs. In 3 A C2 packs, the number of B cards is reduced to 2 cards, or if the pack would have had only one or two B cards to begin with, it will have 1 B card. In 4 A packs, the number of B cards is reduced to 1 card. In C1 packs, a common foil will simply displace a B card (which can result in a pack with no B card).

Uncommons are printed on one sheet with each card appearing twice (and one filler). This is divided into a 66-card A run (with 33 distinct cards) and a 54-card B run (with 27 distinct cards). Packs can have either 2 A cards followed by 1 B card, or 1 A card followed by 2 B cards. Since the runs are unbalanced, 2 A cards happens 13/20 of the time.

Rares are printed on one sheet with each rare card appearing twice and each mythic rare card appearing once. This is divided into a 66-card A run (with 29 distinct rares and 8 mythics) and a 55-card B run (with 24 distinct rares and 7 mythics).

Common Runs

The A common run consists of 33 different cards each appearing twice. The choice of first card is mostly arbitrary.

The B common run consists of 22 different cards each appearing three times. The choice of first card is mostly arbitrary.

The C1 common run consists of 27 different cards each appearing twice plus Golem Foundry, the short-printed common. The choice of first card is mostly arbitrary.

The C2 common run consists of 18 different cards each appearing three times plus Golem Foundry, the short-printed common. The choice of first card is mostly arbitrary.

Uncommon Runs

The A uncommon run consists of 33 different cards each appearing twice. The choice of first card is mostly arbitrary.

The B uncommon run also consists of 27 different cards each appearing twice. The choice of first card is mostly arbitrary.

Rare Runs[1]

The A rare run consists of 29 rares each appearing twice and 8 mythic rares. The choice of first card is mostly arbitrary.

The B rare run consists of 24 rares each appearing twice and 7 mythic rares. The choice of first card is mostly arbitrary.

Token Run

Most of the marketing cards in Scars of Mirrodin have a token or tip on the front face. They are printed on an 11 × 11 sheet with different items appearing different numbers of times. The choice of first card is mostly arbitrary.

Token Rarity
Wurm × 1	Wurm × 1	Cat × 5
Wolf × 5	Imprint Tip Card × 7	Infect Tip Card × 7
Metalcraft Tip Card × 7	Poison and Emblems Tip Card × 7	Proliferate Tip Card × 7
Goblin × 8	Golem × 8	Soldier × 8
Insect × 10	Myr × 15	Poison Counter × 25

Foil Rare Sheet

There is a picture of the foil rare sheet available. [2] Each rare card appears twice, and each mythic rare card appears once.

[1] The rare runs for US Scars of Mirrodin were originally published by Ross Edwards in The Card Wizard's Black Book: Second Edition. They were also separately decoded in the MTG Salvation box mapping thread by jarsyl using community-provided data.
