Most of my teaser clues about Innistrad have been solved, but one still seems to be causing discussion. Which card was inspired by a white Un- card? The answer is that
Nevermore was inspired by this card: {
Look at Me, I'm the DCI.img}.
During Innistrad design, I was making curses, and I thought it might be fun to turn
Look at Me, I'm the DCI into a curse. I eventually removed the card from Innistrad because we decided at one point that to play up the plight of the humans against the monsters that we'd keep the "evil" parts of the design out of white.
Several months later, Erik Lauer is telling me that he wants to find a way to do in white what
Cranial Extraction does in black. Cards like this are good safety valves to make sure that there are answers to environments if a particular card ends up too strong. I tell him that I have already made the card and that it's a 99 in the Innistrad file. (Cards that have been kicked out a file get their codes changed to 99 so that we can see what's been removed in case we want to put it back in.) Erik, as lead developer of Innistrad, put the card back in the set, but turned it from an enchant player (as all the curses are) to a general enchantment.
