Play Booster

Magic Play Boosters are a type of booster product introduced for Murders at Karlov Manor in 2024 to replace both Draft boosters and Set boosters. Going forward, they are the "foundation product" of every premier and tentpole set.
==Description==
Play Boosters are 14-card Booster packs that contain eight "slots" (or card options) six cards are common cards, one is a common that has a 12.5% chance to be replaced with a card from The List, three cards are uncommons, one is a rare or mythic rare, two cards are "wildcards" that can be of any rarity, and one card is a basic land. In addition, Play Boosters also include one non-playable card, with a chance for that to be an art card. Each of the 14 playable cards can be drafted, meaning The List and Special Guests form part of the Limited environment.
Play Boosters are designed to combine the characteristics of their predecessors; they are draftable per Draft Boosters while retaining the fun opening experience of finding surprise cards or card treatments per Set Boosters. The original structure of the Play Booster's slots result in each pack having one rare or mythic rare 58% of the time, two 37% of the time, three 4% of the time, and the chance four rares or mythic rares (1 regular rare/mythic, 2 wildcards and a card from The List/Special Guest) less than 1% of the time. However, these chance were reduced to sets down the line.
Play Boosters do not prevent future sets from having a Bonus sheet but how they are integrated into the pack has not been outlined.
A booster box of Play Boosters origninally contained 36 packs. Starting with Aetherdrift it was reduced to 30 packs.
At their introduction, Play Boosters were priced approximately the same as Set Boosters were prior to their discontinuation.
As of Aetherdrift, Play Boosters no longer contain ad cards.
===Magic Online===
Magic Online implements Play Boosters as they are in tabletop with no changes.
===MTG Arena===
In alignment with tabletop, starting with Murders at Karlov Manor, limited packs on MTG Arena include the same features as a Play Booster. Without foil renderings, that dedicated slot is a second wild card slot. Packs for Limited play events (Draft and Sealed) include Special Guests and cards from The List but because MTG Arena's eternal formats are different from those of tabletop Magic, the designers of MTG Arena have worked with the Play Design team on a few card swaps on The List when necessary.
===Structure===
All playable slots (#1-14) have a chance for the card to be a Booster Fun version.
As of Bloomburrow, the composition is as follows:
Slot 	Quantity	Type 	Chance of surprise
#1-6 	6 	Common 	
#7 	1 	Common or The List 	
*98.5% chance of a common from the set
*1.5% chance of a Special Guest card
#8-10	3 	Uncommon 	
#11 	1 	Non-foil Wildcard 	A card of any rarity from the set. Guaranteed to be non-foil.
#12 	1 	Rare or Mythic Rare 	
*87.5% chance of a rare
*12.5% chance of a mythic rare
#13 	1 	Basic land 	In sets with no basic lands, this will be a common land.
#14 	1 	Foil Wildcard 	A card of any rarity from the set. Guaranteed to be foil.
#15 	1 	Token, art card, play aide	Non-playable card, excluded for draft.
*65% – Token/Helper card
*30% – Art card
*5% – Art card with signature
==History==
===Background===
In September 2023, Mark Rosewater first indicated that the introduction of Set Boosters alongside Draft Boosters had created a number of compounding issues.
 Set Boosters had proved so popular with players that they were significantly outselling Draft Boosters. This put pressure on local game stores (LGSs) to stock Set Boosters at the expense of Draft Boosters. In some smaller regions, this resulted in LGSs only stocking Set Boosters and being unable to run Limited events. For those that did stock both, it cause problems with inventory management as ordering too much of one booster type, or not enough of the other, resulted in a loss of profit. At the same time, the number of games of Limited being played had steadily increased year-on-year since 2020. Based on its internal numbers, Wizards of the Coast projected that without change, the pressure on LGSs to stock Set Boosters would eventually lead them all to abandon purchases of Draft Boosters.
The decision to combine Draft Boosters and Set Boosters into a single product was announced in October 2023. This removed the need for players and LGSs to choose between Set and Draft boosters.
===Initial design===
With Set Boosters being the more popular booster option, R&D decided to move the draft booster closer in design to Set Boosters. Through their market research and player feedback, R&D identified that the likelihood of getting 1-4 rares and/or mythic rares in a pack was the top reason for why players like Set Boosters. This put a limit on the number of cards in the new booster and the type of slots available in the pack. R&D settled on a 14 card booster as the best mix of draft play-ability and Booster Fun.
To facilitate the reduction in cards, the way sets were designed for limited needed to be modified. At the highest level, the number of cards per pack was reduced from 15 to 14 and the number of common cards per pack from 10 to 7. To compensate, the number of common cards in a set was reduced to 81, from 101, to keep the frequency of seeing any one individual common at approximately the same rate. To balance the frequency of commons with that of uncommons, the number of uncommon cards in a set was increased to 100 (from 80).
The intent was to reduce the number of draft chaff common cards and common cards that are specifically designed as sideboard options across the set while increasing the number of answers to bomb rare and mythic rare cards. On the other hand, the collation only allows R&D to guarantee four colors and not five.
Unlike Set Boosters, Play boosters didn't include booster-only Commander cards.
===Adjustments===
Starting with Bloomburrow, "de-archived cards", commonly known as The List cards, which feature the Planeswalker stamp in the bottom-left corner would no longer appear in Play Boosters. The cards found on The List in Bloomburrow are solely Special Guests cards.
Originally, slot 7 would have a 87.5% chance of a common from the set and 12.5% chance of a List card (9.38% – A common or uncommon reprint from The List, 1.56% – A rare or mythic rare reprint from The List, and 1.56% – A Special Guests card). This was changed to 98.5% of it being a common, and 1.5% chance of getting a Special Guest.
With this adjustment, the chance of getting two rares in a Play Booster went down from 37% to 23%. The chance of getting three rares went down from 4% to 1%. The chance of getting four rares went down from less than 1% to negligible.
