'''''Core Set 2020''''', also known as '''''Core 2020''''', is the nineteenth ''[[Magic: The Gathering|Magic]]'' [[core set]]. It was released on July 12, 2019.<ref>{{DailyRef|news/announcing-core-set-2020-and-commander-2019-edition-2019-02-21|Announcing Core Set 2020 and Commander (2019 Edition)|[[Blake Rasmussen]]|February 21, 2019}}</ref> 

==Set details==
[[File:Core Set 2020 Booster box.jpg|right|400px]]
''Core Set 2020'' features a mix of new and [[reprint]]ed cards. The set contains 280 cards (20 basic land, 112 common, 80 uncommon, 53 rare, and 15 mythic rare) and includes randomly inserted [[premium]] versions of all cards. 1:45 cards are foil, instead of the usual 1:67.<ref name="15 changes">{{WebRef|url=https://wpn.wizards.com/en/article/m20-15-changes-every-retailer-should-know|title=M20: 15 Changes Every Retailer Should Know|date=June 13, 2019|publisher=[[Wizards Play Network]]}}</ref> A unique [[Buy-a-Box]] promotional card numbered #281/280 is also considered to be part of the set. 63 additional cards are found in the set's [[planeswalker deck]]s (#282/280 to #301/280) and [[Core Set 2020/Spellslinger Starter Kit|Spellslinger Starter Kit]] and [[Core Set 2020/Welcome decks|Welcome decks]] (#302/280 to #344/280).<ref name="Release Notes"/> ''Core Set 2020'' introduced [[full-art]] [[token]]s.<ref name="Tokens"/> The [[Gainland]]s appear like the taplands in Core 2019 over the basic lands in about 5/12 boosters.

[[Chandra Nalaar]] is the face of ''Core Set 2020'' card set, and is represented by three different planeswalker cards in different rarities and depicting several facets in her life.<ref>{{WebRef |url=https://io9.gizmodo.com/get-to-know-magics-most-famous-fire-mage-in-these-brand-1835412320|title=Get to Know Magic's Most Famous Fire Mage in These Brand New Cards|author=James Whitbrook|date=June 11, 2019|publisher=Io9.gizmodo.com}}</ref><ref name="Journey">{{TwitterRef|wizards_magic|1138505814426021893|author=[[Magic: The Gathering]]|title=Chandra is the only Planeswalker in M20 getting an uncommon and rare card - she's the face of the set and her journey is all over M20. |date=June 11, 2019}}</ref> A fourth Chandra planeswalker card is included in the Chandra Planeswalker Deck.<ref name="Release Notes">{{DailyRef|feature/core-set-2020-release-notes-2019-06-25|''Core Set 2020'' Release Notes|[[Wizards of the Coast]]|June 25, 2019}}</ref> 

===Rules change===
Starting with [[tabletop]] ''Core Set 2020'' Preleases on July 5, the [[Mulligan#London mulligan|London mulligan]] will be used for all play.<ref name="Release Notes"/> It became officially reflected in the [[Comprehensive Rules]] with the M20 rules updates on July 12.<ref>{{DailyRef|news/london-mulligan-2019-06-03|The London Mulligan|[[Ian Duke]]|June 3, 2019}}</ref> To take this mulligan, a player [[shuffle]]s the cards in their [[hand]] back into their [[library]], draws a new hand of cards equal to their starting hand size, then puts a number of those cards equal to the number of times that player has taken a mulligan on the bottom of their library in any order.

===Storyline===
''Core Set 2020'' has a small flavor theme focusing on the life of [[Chandra Nalaar]].<ref name="Journey"/><ref name="Core Point"/> There are no [[Story Spotlight]]s, and there was no story support for the set.

===Marketing===
''Core Set 2020'' is sold in 16-card [[boosters]] (one card being a [[marketing card]]), mono-colored [[theme booster]]s, five [[welcome deck]]s, five [[planeswalker deck]]s, the ''Core 2020'' [[bundle]], a [[Core Set 2020/Deck Builder's Toolkit|Deck Builder's Toolkit]], a [[Core Set 2020/Spellslinger Starter Kit|Spellslinger Starter Kit]] and a [[Land Station]]. The bundle for the first time contains a [[alternate art]] [[foil]] [[promo]] card and an oversized [[spindown life counter]].<ref>[https://wpn.wizards.com/en/products/core-set-2020 WPN info]</ref> It also contains 20 [[foil]] [[land]]s.<ref name="15 changes"/> The boosters feature key art of three planeswalkers ([[Ajani]], [[Mu Yanling]] and [[Sorin Markov]]) that is also featured on the Planeswalker decks and Welcome decks.

Like with its [[Core Set 2019|predecessor]], the Welcome decks, Planeswalker decks and Deck Builder's Toolkit are strongly integrated, which allows for an easier transition between the products.<ref name="Core Point"/><ref>{{WebRef|url=https://wpn.wizards.com/en/article/getting-new-players-magic-easier-ever|title=Getting New Players Into Magic is Easier Than Ever|author=[[WPN]]|date=June 26, 2019|publisher=[[Wizards Play Network]]}}</ref> The [[Spellslinger Starter Kit]] is now also part of the line up.<ref>{{WebRef|url=https://wpn.wizards.com/en/article/mark-heggen-rds-plan-make-new-magic-players|title=Mark Heggen: R&D's Plan to Make New Magic Players|author=[[WPN]]|date=June 26, 2019|publisher=[[Wizards Play Network]]}}</ref> Throughout the product line the colors have a central theme: {{W}} [[Lifegain]], {{U}} [[Flying]], {{B}} [[Vampire]]s, {{R}} [[Direct damage]] and {{G}} [[Fatty|Big Monsters]]/[[Pump]].

==Themes and mechanics==
To improve [[draft]], ''Core Set 2020'' is built around three-color "[[wedge]]s" (a color and its two enemies).<ref name="Core Point">{{DailyRef|making-magic/core-point-2019-06-17|Core to the Point|[[Mark Rosewater]]|June 17, 2019}}</ref> 

The set features the following [[limited]] [[archetype]]s, which focus on the ally-colored pairs within each wedge:
*{{mana|WBG}}: [[Go wide|Go Wide]] 
**{{mana|WG}}: <c>Ironroot Warlord</c>
*{{mana|URW}}: [[Flying]] Creatures 
**{{mana|WU}}: <c>Empyrean Eagle</c>
*{{mana|BGU}}: [[Control deck|Control]] with "[[Enters the battlefield|Enters-the-Battlefield]]" Effects 
**{{mana|BU}}: <c>Tomebound Lich</c>
*{{mana|RWB}}: [[Aggro]]
**{{mana|BR}}: <c>Ogre Siegebreaker</c>
*{{mana|GUR}}: [[Elemental]] Creatures 
**{{mana|GR}}: <c>Creeping Trailblazer</c>

The enemy colored signposts connecting the two archetypes which they are part of:
*{{mana|WB}}: <c>Corpse Knight</c> (Going Wide Aggro)
*{{mana|UR}}: <c>Lightning Stormkin</c> (Flying Elementals)
*{{mana|BG}}: <c>Moldervine Reclamation</c> (Going Wide recursive midrange value)
*{{mana|RW}}: <c>Skyknight Vanguard</c> (Flying Aggro)
*{{mana|GU}}: <c>Risen Reef</c> (Elemental with "Enters-the-Battlefield" Effect)

'''[[Protection]]''' returns back to evergreen on a probationary status.<ref name="Protection">{{EzTumblr|https://markrosewater.tumblr.com/post/185685198983/your-article-on-core-2020-specifies-that-there-are|title=Did R&D change their mind on protection being removed from evergreen?|June 18, 2019}}</ref><ref>{{EzTumblr|https://markrosewater.tumblr.com/post/185685167758/protection-is-back-i-mean-i-love-that-but-how|title=Protection is back? i mean, i love that, but how come?|June 18, 2019}}</ref>

==Notable cards==
*<c>Bag of Holding</c> is a ''[[Dungeons & Dragons]]'' crossover.
*<c>Ripscale Predator</c> is printed as a [[Dinosaur]] for the first time after being originally printed as a [[Lizard]] in ''[[Gatecrash]]'', and the [[oracle]] change in the ''[[Ixalan]]'' update.
===Banned and restricted cards===
* <c>Mystic Forge</c> is a <c>Future Sight</c>-inspired card that worked only with artifacts and colorless spells. Naturally, the artifact-heavy Vintage format found this to be extremely powerful, giving the Stax decks a card advantage engine that competes with the other decks in the format. It was subsequently restricted in August 2019.
* <c>Field of the Dead</c> was initially one of three cards believed to be a "last hurrah" type card (for <c>Scapeshift</c> in particular), alongside <c>Sorin, Imperious Bloodlord</c> for tribal [[Vampire]]s and <c>Marauding Raptor</c> for tribal [[Dinosaur]]s, before Scapeshift rotated out. After Scapeshift rotated, the deck would fetch additional copies of Field of the Dead with <c>Golos, Tireless Pilgrim</c> and use <c>Circuitous Route</c> to locate specifically named lands.  However, rotation also caused the cards that kept Field in check to leave Standard, which allowed Field decks to dominate due to their incredible consistency.  Field of the Dead was later banned for being too powerful after the release of ''[[Throne of Eldraine]]''.<ref>{{WebRef|url=https://www.hipstersofthecoast.com/2019/10/bant-golos-dominates-week-1-standard/|title=Bant Golos Dominates Week 1 Standard|author=David McCoy|date=October 10, 2019|publisher=[[Hipsters of the Coast]]}}</ref><ref>{{WebRef|url=https://www.hipstersofthecoast.com/2019/10/field-of-the-dead-banned-in-standard/|title=Field of the Dead Banned in Standard|author=David McCoy|date=October 21, 2019|publisher=[[Hipsters of the Coast]]}}</ref> Its power level as an inevitability engine permeated through Pioneer, where it was banned in the first cycle in December 2019; Historic, which banned it August 2020; Modern, where it was banned February 2021; and [[Historic Brawl]], where it was banned December 2021.
* <c>Leyline of Abundance</c> is a combo-centric Leyline that encouraged using mana dorks to get ahead rather than land-based options, ostensibly as it would be weaker to disruption. However, the first Pioneer bannings included this card as mono-Green ramp was dominant. R&D intended for aggressive bannings early on in the format, and while Leyline was not outside the realm of the format's power level, it has yet to be revisited.
* <c>Veil of Summer</c> is a boosted version of <c>Autumn's Veil</c>, a previous colour hate card that was not effective as a sideboard card as the counter-reactive one-for-one played poorly against the card-advantage blue and black decks. However, the extra card draw counteracted this, and being in the format with so many three-mana planeswalkers from [[War of the Spark]] meant answers to any form of green deck were at an all-time low. It was later banned in Historic, Pioneer, and Standard, as the potential to counter-play was almost impossible and made blue and black reactive decks unplayable.
* <c>Golos, Tireless Pilgrim</c> was the cornerstone of Field of the Dead decks and has continued to be a playmaker in Modern, but it was banned in [[Brawl]] and [[Commander]]. As a commander it entails no specific deck design due to its five-color identity, effectively negates commander tax with its ETB ability, and is also a value engine.
* <c>Agent of Treachery</c> is the latest in a long string of <c>Confiscate</c>-type designs, stretched up to seven mana to "compensate" for the fact that the ability is otherwise permanent. The fact that it was on a creature's triggered ability made it far too easy to trigger the ability outside of casting it, notably in the format with <c>Winota, Joiner of Forces</c>, <c>Lukka, Coppercoat Outcast</c>, <c>Elspeth Conquers Death</c> and <c>Yorion, Sky Nomad</c>. <c>Fires of Invention</c> also made it so that several of these options could be done at once, and especially when assisted with <c>Teferi, Time Raveler</c>. The deck borne of this strategy was banned in June 2020 in three ways — Agent, Fires and the companion rules change all took out an axis of the deck. Both Agent and Fires were banned out of Historic a month later.
* <c>Kethis, the Hidden Hand</c> is the namesake engine behind the 4C [[Legendary]] Kethis combo deck, utilising <c>Mox Amber</c> as a free, legendary mana source alongside graveyard fuel generated by <c>Emry, Lurker of the Loch</c> or <c>Diligent Excavator</c>. While the deck in Standard rotated when Mox Amber did, and the Historic version was allowed to continue, it was banned in Pioneer rather pre-emptively to show that those sorts of combo decks were not welcome in the format.
