Modern Masters 2015 Collation

Modern Masters 2015 is a large set with 101 commons, 80 uncommons, 53 rares, and 15 mythic rares. This is the normal size for a large set of this era. Every pack contains a foil card. The set was printed in the USA.

Modern Masters 2015 was sold in 15 card booster packs (which contain an additional ad card). Booster boxes have 24 packs. Notably, the English printing uses recyclable paperboard booster packaging, but the collation is the same even for non-English boosters using the traditional booster packaging.

Pack Anatomy

This set uses sequential collation in a novel configuration.

Packs have back-facing cards with common-uncommon-rare ordering followed by a foil card. The ad card is at the beginning, and is reversed (so the ad side is visible rather than the token side).

There are four common runs: A, B, C, and D. The A and C runs have 22 distinct cards each repeated five times. The B run has 39 cards each repeated three times, and the D run has 18 cards each repeated six times. Packs have 2-3 A cards followed by 3-4 B cards, 2-3 C cards, and 1-2 D cards. Packs can be 2+4+2+2, 2+4+3+1, 3+3+2+2, or 3+4+2+1. (I believe 2+3+3+2 and 3+3+3+1 will never occur.) Assuming all commons are equally likely, these pack types should occur respectively at 65/101, 18/101, 14/101, and 4/101. (These are empirically plausible.)

There are two uncommon runs, A and B, each with 40 different cards appearing three times each. Half of packs have two A cards followed by a B, and half have one A card followed by two B cards.

There are five foil sheets: a common sheet, two uncommons sheets that match the non-foil uncommon sheets, a rare sheet, and a mythic sheet. I didn't have enough data to fully calculate the foil collation pattern, but it seems likely that the overall rarity breakdown is the same as contemporary masters sets: commons appear 5/7 of the time, uncommons appear 3/14 of the time, and rares (or mythic rares) appear 1/14 of the time. (This matches pretty well empirically.) Because the rares and mythics are on separate sheets, the mythic rate is probably 1/8 (certainly not 15/121).

Common Runs

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

The B common run consists of 39 different cards each appearing three times. The cards alternate between white, black, and blue. The choice of first card is mostly arbitrary.

The C common run consists of 22 different cards each appearing five times. The cards alternate between red and green. The choice of first card is mostly arbitrary.

Note that the two copies of Smash to Smithereens in the last row are close enough to appear in the same pack.

The D common run consists of 18 different cards each appearing six times. The choice of first card is mostly arbitrary.

Uncommon Runs

The A uncommon run consists of 40 different cards each appearing three times. This matches one of the foil uncommon sheets (although I can't confirm the alignment is the same, that is assumed). [1] The order of the run is reverse relative to the sheet. (The filler card image is not a scan.)

The B uncommon run also consists of 40 different cards each appearing three times. This matches one of the foil uncommon sheets (although I can't confirm the alignment is the same, that is assumed). [1] The order of the run is reverse relative to the sheet. (The filler card image is not a scan.)

Token Run

All of the marketing cards in Modern Masters 2015 have a token, emblem, or tip card on the front face. They are printed on 110 card sheet with different items appearing different numbers of times.

Token Rarity
Golem × 2	Worm × 2	Elephant × 3
Myr × 3	Snake × 3	Insect × 4
Spirit × 4	Eldrazi Spawn × 5	Eldrazi Spawn × 5
Eldrazi Spawn × 5	Wolf × 6	Faerie Rogue × 9
Germ × 9	Soldier × 9	Thrull × 9
Saproling × 14	Modern Tip Card × 18

Foil Common Sheet

There is a picture of the foil common sheet available. [1] Each common card appears once. The order of the run is reverse relative to the sheet. (The filler card image is not a scan.)

Foil Uncommon Sheets

The foil uncommons sheet layouts are given for the non-foil uncommon sheets. These layouts are assumed to be the same.

Foil Rare Sheets

There is a picture of the foil rare sheet available. [2] Each rare card appears twice. The order of the run is reverse relative to the sheet. (The filler card image is not a scan.)

There is a picture of the foil mythic sheet available. [1] Each mythic rare card appear eight times. The order of the run is assumed to be reverse relative to the sheet. (The filler card image is not a scan.)
