Magic: The Gathering Arena or MTG Arena is a free-to-play digital collectible card game developed and published by Wizards of the Coast (WotC). The game is a digital adaption based on the Magic: The Gathering (MTG) card game, allowing players to gain cards through booster packs, in-game achievements or microtransaction purchases, and build their own decks to challenge other players. The game was released in a beta state in November 2017, and was fully released for Microsoft Windows users in September 2019, and a macOS version on June 25, 2020. Mobile device versions were released in March 2021. MTG Arena follows the same rules as the physical card game, in which players use decks of cards that include land cards that generate five separate colors of mana, and play cards that consume that mana to summon creatures, cast offensive and defensive spells, and/or activate effects and abilities. Players battle other players using a selected deck, with the goal of reducing the opponent's life-total to zero before their opponent can do the same to them. MTG Arena supports both Constructed Deck play and Limited play. In Constructed play, players create decks of cards from their library. The game gives new players a library of base cards and pre-made decks from those cards, but as players win matches or complete daily quests, they can earn new booster packs that add cards to their library, and allow players to then customize their decks and improve them. Unlike most physical packs of Magic cards and those used in Limited events which usually contain 15-16 playable cards, purchased packs in MTG Arena contain 8 cards (1 rare, 2 uncommon, and 5 common).[1] In Booster Draft, the most common form of Limited play, players compete with several other players by sequentially selecting and obtaining cards from packs provided by the game. Those cards are then used to create a Limited deck used for the event. An additional Limited format called Sealed allows players to open a set number of special booster packs and build a deck only with cards from those packs. In both varieties of Limited, players attempt to win as many matches as they can with that deck. In best-of-one, the event ends once the player has either won 7 or lost 3 matches. In best-of-three, the event ends after the player completes three matches, regardless of their outcome. In most Limited events, the player keeps all the cards drafted and adds them to their library, and there are generally prizes based on wins that may give booster packs or in-game currency as a reward.
