Masters 25 Collation

Masters 25 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.

Masters 25 was sold in 15 card booster packs (which contain an additional ad card). Booster boxes have 24 packs.

USA Pack Anatomy

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

Packs have back-facing cards with common-uncommon-rare ordering followed by a foil card and ad card.

Packs are evenly split between C1 commons and C2 commons. C1 packs will contain 2×A + 2×B + 6×C or 3×A + 2×B + 5×C. C2 packs will contains 4×A + 2×B + 4×C or 4×A + 3×B + 3×C.

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.

In the foil slot, 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.

Common Runs

The A common run consists of 33 different cards each appearing twice. These cards are white, black, and red (appearing in that order). The choice of first card is mostly arbitrary.

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

The C1 common run consists of 27 different cards each appearing twice plus Lull, the short-printed common. It includes cards of all colors and colorless cards. The choice of first card is mostly arbitrary.

The C2 common run consists of 18 different cards each appearing three times plus Lull, the short-printed common. It includes cards of all colors and colorless cards. The choice of first card is mostly arbitrary.

Uncommon Runs

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

The B uncommon run also consists of 40 different cards each appearing three times. The choice of first card is mostly arbitrary.

Token Run

All of the marketing cards in Masters 25 have a token on the front face. They are printed on an 11 × 11 sheet with different items appearing different numbers of times. Some copies of the Fish token have a Kraken token on the back instead of an advertisement. Of the four on the sheet, the first has a Kraken on the back, the next two do not, and I haven't been able to make a determination for the last one. (The data is presented assuming the last one also has an ad on the back.)

Foil Common Run

The foil common run consists of each common card appearing once. The choice of first card is mostly arbitrary.
