Collecting Edge of Eternities: The Four Most Important Things to Know

I promise a rewrite of the probabilities listed in this article, with no room for rounding errors or waving offs like “less than 1%”.

Play boosters

• 6–7 Commons

  • There are 81 commons from Edge of Eternities that can be found in these slots.
  • In 1.8% of Play Boosters, 1 of 10 non-foil Special Guests cards will replace a common. Of note, Special Guests cards aren't found in the wildcard nor traditional foil slot in Play Boosters.

• 3 Uncommons

  • There are 100 uncommons from Edge of Eternities that can be found in these slots.

• 1 Wildcard of any rarity

  • A common (12.5%), uncommon (62.5%), rare (10.6%), or mythic rare (less than 1%) from Edge of Eternities's main set (EOE default frame cards)
  • A rare (10%) or mythic rare (2.5%) Stellar Sights land
  • A rare (1%) or mythic rare (less than 1%) borderless viewport land
  • A rare (less than 1%) or mythic rare (less than 1%) borderless triumphant or surreal space card

In better words, imagine the slot is divided into 8 parts.

Part 1 is a common.

Part 2, 3, 4, 5 and 6 are uncommons.

Part 7 is the bonus sheet.

Part 8 is the rare or mythic. More analysis of this part is below, with the rare slot.

• 1 Rare or mythic rare card
  • There are 60 rares and 20 mythic rares from Edge of Eternities that can be found in these slots.
  • A rare (80.4%) or mythic rare (14.2%) from Edge of Eternities's main set
  • A rare (2%) or mythic rare (less than 1%) borderless triumphant card
  • A rare (2%) or mythic rare (less than 1%) borderless surreal space card
  • A mythic rare (less than 1%) borderless viewport land

In total, these rare slots are a mess to figure out, I’ll only present my theories using some assumptions:

Relative to 12.5%, the two less than 1% figures for the mythic wildcard implies that an individual rare will appears 4 times as often as a rare, putting the ratio overall to 12 rares : 1 mythic (instead of a normal rare slot’s 2:1 individual rate and 6:1 overall rate).

Any rare or mythic with an applicable set of showcase versions can be upgraded at a rate of 12.5%. One card with two showcase versions will then split that rate between its versions.

This fact will put each treatment at the following rates. The total space’s size is $140 * 8 = 1,120$.

To best match the rounded numbers, we’ll put the rare viewport cards in the wildcard slots while leaving all other cards in the rare slot.

This however would change the probability of the rare slot. The mythic slot may prove to be a fluke however, 14.2% out of the possible 14.287% (1/7) is insane and leaves basically no space for showcase mythics.

• 1 Traditional foil card of any rarity

  • A common (58%), uncommon (32%), rare (6.4%), or mythic rare (1.1%) from Edge of Eternities's main set
  • A rare (1%) or mythic rare (less than 1%) Stellar Sights land
  • A rare (less than 1%) or mythic rare (less than 1%) borderless viewport, triumphant, or surreal space card

• 1 Land

  • A non-foil (64%) or traditional foil (16%) default frame basic land
  • A non-foil (16%) or traditional foil (4%) borderless celestial basic land

Each individual vertical art basic land is twice as rare as each individual horizontal art basic land.

Any cards here can independently be upgraded to foil at a rate of 20%.

Collectors’ Boosters

• 5 Traditional foil commons
  • There are 81 commons from Edge of Eternities that can be found in these slots.
• 4 Traditional foil uncommons
  • There are 100 uncommons from Edge of Eternities that can be found in these slots.

The probability for a specific common to be pulled this way is 1 in 16.2. While the probability for a specific uncommon to be pulled this way is 1 in 25. This puts each uncommon at about 1.5432 times as rare as each common.

• 1 Traditional foil (66.6%) or galaxy foil (33.3%) celestial basic land

In another word, the ratio between the two foilings are 2:1.

• 1 Traditional foil default frame rare (86%) or mythic rare (14%) card

In another word, the ratio between the two rarities are 6:1. The total pool size is 140 cards.

• 1 Non-foil card from Edge of Eternities Commander
  • 4 Mythic rare borderless cards (9%)
  • 20 Rare extended-art cards (91%)

In another word, the ratio between the two rarities are 10:1. The total pool size is 88 cards, so 1.5909 times more common than the draft set.

• 1 Non-foil Booster Fun card
  • A rare (47%) or mythic rare (5%) extended-art card from the Edge of Eternities main set
  • A rare (7%) or mythic rare (4%) borderless viewport land
  • A rare (17%) or mythic rare (3%) borderless triumphant card
  • A rare (15%) or mythic rare (2%) borderless surreal space card

Using prior knowledge and more about the extended cards, we can draw a table of exact probabilities in this slot:
