As part of the new player experience in MTG Arena, you can unlock 10 2-color decks by completing quests. Once you complete one of these quests, you’ll be assigned a new one within 24 hours.
There’s currently a visual bug in which some players see the timer as “0:00:00” instead of the real countdown time. Don’t worry! You’ll still get a new quest within 24 hours. We plan to fix the countdown display bug in an upcoming release and thank you for your patience.
If you do run into any issues, please reach out to us here.
