Dark Ascension is a small set with 60 commons, 40 uncommons, 35 rares, 10 mythic rares, and 13 double-faced cards. Innistrad basic lands also appear in packs but are not considered part of the set. This is the normal size for a small set of this era with the addition of doubled-faced cards. 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.
Dark Ascension was sold in 15 card booster packs (which contain an additional ad card). Booster boxes have 36 packs.
The US printing uses sequential collation.
Packs are back-facing and have only 9 commons followed by 3 uncommons, a rare, and an ad card. The last two cards will be a double-faced card and either a basic land or a checklist. A checklist will be before the double-faced card and a basic land will be after it. If there is a foil, it will be the last card, displacing a common. (Unlike Innistrad, foil double-faced cards also displace commons.)
|9 Commons||3 Uncommons||1 Rare||1 Ad Card||1 Checklist||1 DFC|
|9 Commons||3 Uncommons||1 Rare||1 Ad Card||1 DFC||1 Land|
|8 Commons||3 Uncommons||1 Rare||1 Ad Card||1 Checklist||1 DFC||1 Foil|
|8 Commons||3 Uncommons||1 Rare||1 Ad Card||1 DFC||1 Land||1 Foil|
The commons 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). Each pack contains 5 A commons followed by 4 B commons.
Foils displace common cards. Note that foil basic lands do not appear. Foil uncommons displace B commons, and all other foils replace A commons. If we assume that all commons are equally common (which is even more credible if the two common runs are printed on the same sheet), this allows us to calculate the foil uncommon rate from the total fail rate. If we take 15/68 as the total foil rate, then the foil uncommon rate would be 67/1360.
Uncommons are printed on one sheet with each card appearing three times (and one filler). This is divided into a 66-card A run (with 22 distinct cards) and a 54-card B run (with 18 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.
Basic lands appear in 1/4 of packs and checklists occur in the other 3/4.
The double-faced cards are printed on one sheet. The mythic rare appears twice, the rares appear three times, the uncommons appear nine times, and the commons appear eighteen times. (This fills the sheet.) The sheet is divided into a 66-card run (with one rare, three uncommons, and two commons) and a 55-card run (with the mythics, two rares, one uncommons, and two commons).
Rarities of double-faced common, uncommon, and rare cards are very close to the corresponding rarities of normal cards. Double-faced mythics, however, and about 32% more common than normal mythics.
The A common run consists of 33 different cards each appearing twice. It includes cards of all colors and colorless cards. The choice of first card is mostly arbitrary.
The B common run consists of 27 different cards each appearing twice. It includes cards of all colors and colorless cards. The choice of first card is mostly arbitrary.
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 18 different cards each appearing three times. The choice of first card is mostly arbitrary.
All of the marketing cards in Dark Ascension 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. In some boxes, the sequence is reversed, so the choice of first card and the direction are both mostly arbitrary. Note that some of the tokens have the Innistrad expansion symbol, but not all Innistrad tokens can appear in Dark Ascension.
