Play Booster Fact Sheet: Modern Horizons 3

General Information

  • The make up of this set is a little bit complicated in some small ways, so I plan to update this article regularly as more information comes in or is clarified. If I am not sure about any of the details in this article I intended to note which part I’m not clear about.
  • There are 80 total Commons in this set.
  • There are 101 total Uncommons in this set.
    • 81 of these are single-faced cards.
    • 20 of these are double-faced cards.
  • There are 60 Rares in this set.
  • There are 20 Mythic Rares in this set.
    • 15 of these are single-faced cards
    • 5 of these are double-faced cards.
  • 20 Uncommons, 18 Rares, and 4 Mythic Rares are from Commander or Legacy sets and are new-to-Modern.
  • There are 6 Basic Lands in this set.
    • Plains
    • Island
    • Swamp
    • Mountain
    • Forest
    • Snow-Covered Wastes
      • This is an Uncommon in the set and is included in the 101 Uncommon count above.
  • There is no iteration of The List in MH3.
  • There are 10 Special Guests in this set that will appear ~1 in every 64 Play Boosters (or ~1.56% of packs).
  • Play Boosters will also contain all 8 borderless profile Commanders from the Modern Horizons 3 Commander decks.
    • I believe these will show up with the MH3 Commander Set Symbol on them, but if you open them in a Play Booster they will be legal in Limited.
    • These are confirmed to be coming to Arena.
  • 58 cards (7 Commons, 16 Uncommons, 26 Rares, and 9 Mythic Rares) will get the retro frame treatment.
    • An additional 16 reprints from Modern Horizons and Modern Horizons 2 (2 Commons, 6 Uncommons, 2 Rares, and 6 Mythic Rares. These will have a set code of “H2R”, and I believe the H2R cards will not be appearing in Play Boosters. However the article is not fully clear on this point and I’m working to get confirmation one way or the other.
  • Full Art lands will appear in Play Boosters in ~1 out of every 6 packs (or ~16.67% of packs)
    • In ~10% of Play Boosters this will be a normal Full Art land.
    • In ~6.67% of Play Boosters this will be a traditional foil Full Art Land.
  • In a “small number” of English-language MH3 Play Boosters, some of the foil double-faced Uncommons were misprinted. According to WOTC these misprints have non-matching front and rear faces. They should be treated as if they are the card depicted on the front face.
  • There does not appear to be a token/art card/ad card slot in Play Boosters.

    • ~6.7% of the time this will be a full-art, foil Eldrazi Basic Land.
  • Slots 8-10: Always an Uncommon, but any (or all) of these could be either single-faced or double-faced.
    • This is broken down as, on average, ~2.4 Uncommons in each pack will be single-faced and ~.6 Uncommons in each pack will be double-faced
  • Slot 11: Always a Rare or Mythic Rare. This is broken down as follows (hold tight, it’s going to be a bumpy ride from here on out):

    • ~4.2% of the time this will be a “Commander Mythic Rares (…both regular and borderless…) double-faced cards, and more.”
      • This is a little unclear, and when I inquired about a clarification I was told “It is challenging to give more details. I have to make sure I am not spoiling anything.” I believe this is saying that this is the slot where the Commander Face cards can appear, but I don’t believe any of these are double-faced cards so I’m not 100% certain.
    • <.1% of the time this will be a Full-art Snow-Covered Wastes.
  • Slot 14: Always a foil card, but can be of any rarity.
    • This can contain traditional foil versions of the New-To-Modern cards, retro frame New-to-Modern cards, and traditional foil versions of everything in the wildcard slot. This is not further broken down the way Slot 13 was, but I would expect the breakdown to be roughly the same as above.
