We all heard about the "god packs" during Journey into Nyx prereleases. The awesome packs that rather than having a normal distribution instead had all 15 god cards. I didn't see one opened myself, but it must have been awesome for those who got one.
Now it seems we have "god boxes" to add to that list.
There's no official word if this is a distribution error or something done intentionally by Wizards. Honestly, I wouldn't be surprised either way. Mistakes in print runs do happen, but on the other hand Wizards is awesome enough to slip something like this in.
What I do know is I don't really care. I just want my next box to look like this.
