Magic: The Gathering Arena entered open beta nearly one year ago, and on Sept. 26 the free-to-play game goes live. To celebrate, developer and publisher Wizards of the Coast is giving players access to hundreds of collectible cards to mess around with for a limited time. Then, in the first week of October, players will compete for the chance to add all of those cards to their digital collections permanently.

Arena is a one-to-one PC recreation of the physical card game. However, unlike the physical game, individual cards aren’t available to trade with other players or to purchase on the secondary market. The only way to get those cards is from Wizards, generally through blind booster packs.

During Arena’s launch weekend, Wizards will give players access to four copies of every Standard-legal card. That includes all the cards from Guilds of Ravnica, Ravnica Allegiance, War of the Spark, Core Set 2020 and Throne of Eldraine for 12 games of Standard played against live players.

Later, on Oct. 6, Wizards will allow players to attempt another 12 games of Standard with the same selection of cards. If they get 12 wins before losing twice, they’ll win one copy of every Standard-legal card.

Most competitive decks include between two and four versions of a given card, so the so-called Win Every Card Challenge won’t make you bulletproof. But, it is a great start. Even if you can’t make it all the way to 12 wins, there are other rewards at lower levels. You’ll earn a free rare card from the Throne of Eldraine set just for participating on Oct. 6. More details will be available in-game, and at the official Magic: The Gathering Arena website.
