to generate mana that allows them to summon creatures and cast spells, with many of the game's other mechanics changed to be performed automatically by the game. Players can earn in-game rewards to get new cards or can acquire these through microtransactions. Magic: The Gathering Arena Magic: The Gathering Arena is a free to play version of MtG, streamlined for quick online play and to be easily used for live streaming. It initially supported Constructed Deck play (using cards earned from boosters by winning games or through microtransactions) and Draft play. It was developed by Wizards' in-house studio, Magic Digital Studio. Arena is aimed to stay concurrent with the physical card game, with plans to release new expansions on the same day they are released physically. The game was extended to be also supported on MacOS June 2020. Magic: Legends Magic: Legends is a free-to-play action role-playing game that was under development by Cryptic Studios and Perfect World Entertainment, but has since been canceled as of June 2021. The game was previously billed as a massively multiplayer online role-playing game (MMORPG). Instead, as an action role-playing game, players control a Planeswalker using abilities that are drawn randomly from an arsenal based on Magic cards, with players able to gain access to new cards through completing quests or through microtransactions. The game launched an open beta preview version for Microsoft Windows in March 2021. While formal releases on Windows, PlayStation 4, and Xbox One were planned later in 2021, this did not come to fruition after negative feedback on the open beta, and the game was canceled. It is expected to become unavailable to players in October 2021 when the servers are closed.

DragonStar Studios got Wizards of the Coast's permission for the product, and it had no copyrighted art in it. Later, Magic Workstation was released; it is similar to Apprentice, but adds more graphical support. Seeing Apprentice's success, some developers went on to implement rules enforcement as part of the game
