Blizzard has announced that the Swift Shorestrider TCG item is now available as the next Amazon Prime Gaming promotion!
Update: Blizzard has deleted the blue post with information on the Swift Shorestrider promotion. Given that the current Epic Purple Shirt promotion is listed as expiring on June 29th, it seems likely that the original release cadence was pushed back a week.
We’re keeping an eye on it, but expect that the Swift Shorestrider will return in a few days!
