Are you looking for an MTG Arena promo code? During the Ixalan pre-release event game stores were given special token cards to hand out to any players who participated in the event. A unique code was printed on each token card that could be used to gain priority access to the MTG Arena beta during sign up. The Ixalan pre-release was not the only time that these promo codes were available. These promo code token cards were also handed out to players to stopped by the MTG Arena booth during 2017 Grand Prix events. Unfortunately, now that these events are over, there is no way to obtain MTG Arena promo codes other than trying to find an unused code that was picked up by someone who did attend one of these events.
If you are still interested in signing up for the MTG Arena beta with priority access, check out our MTG Arena Closed Beta Priority Access Guide!
