Gatecrash Collation

Gatecrash is a large set with 101 commons, 80 uncommons, 53 rares, and 15 mythic rares. This is the same size as Return to Ravnica (expect for basic lands). 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.

Gatecrash 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, a basic land, and an ad card. If there is a foil card, it will appear after the rare, displacing a common.

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

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

A	A	B	B	C1	C1	C1	C1	C1	C1
A	A	A	B	B	C1	C1	C1	C1	C1
A	A	A	A	B	B	C2	C2	C2	C2
A	A	A	A	B	B	B	B	C2	C2

When a foil appears in a pack, it will displace a common card. Common foils displace A commons and only appear in C1 packs. Uncommon foils displace B commons. The fifth variations of each basic land are probably on the foil uncommon sheet and so will displace B commons. Rare foils displace C2 commons.

Uncommons are split into four runs: A, B, C, and D. A and B contain 22 distinct cards each three times, and C and D contain 18 distinct cards each three times. Packs contain one card from any three of the four runs. A uncommons always appear before B which appear before C which appear before D. Mathematically, A and B should appear in 33/40 of packs, and C and D should appear in 27/40 of packs. (Therefore e.g. packs with just B, C, and D should appear 7/40 times.) These rates are plausible.

Basic lands are the basic lands from Return to Ravnica with their original expansion symbols.

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 Skyblinder Staff, 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 Skyblinder Staff, the short-printed common. The choice of first card is mostly arbitrary.

Uncommon Runs

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

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

The C uncommon run also consists of 18 different cards each appearing three times. The choice of first card is mostly arbitrary.

The D uncommon run also consists of 18 different cards each appearing three times. The choice of first card is mostly arbitrary.

Token Run

All of the marketing cards in Gatecrash have a token, emblem, 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. Some of the tokens are from Return to Ravnica printed with that expansion symbol, but not all of those tokens appear here. The guild tip cards from Return to Ravnica are also repeated (but are rarer here).
