Notes
- ↑ There was a bug which makes the reward "Dark Magician Girl" again. This bug has been fixed after the update on 25 April 2013. For the players who have already received the reward, the developers will not remove the second "Dark Magician Girl" reward and replace it with the correct "Red-Eyes Black Dragon" reward.
