Ugin's story

During the Fate Reforged pre-release you get a booster pack which contains 1 land card, 1 token and 2 random alternative cards for completing the event. In paper Magic you could open Ugin, the Spirit Dragon in such pack. When Magic Online players started wondering why the heck no one seemed to be getting any Ugins, Wizards clarified that this card was not given out.

Putting it mildly, the community was not pleased with this announcement. More and more people expressed disapproval what forced Wizards to change their mind. Eventually, Wizards has opted to give random players copies of Ugin based on the number of pre-release they participated. A player's likelihood to get an Ugin, the Spirit Dragon is the same as it is in paper Magic.

The moral of the story: Wizards listen what the community has to say or in other words Wizards care about marketing.
