I can't help but think that players generally expect graveyard recursion spells to behave in a completely controlled manner. (Disentomb effects have been around since the game's beginning.) Was there any discussion about alternatives to making recursion random such as making it appear at a less-than-normal rate or by making it more narrow? You've often mentioned that it's usually best to go with players' expectations and I can't help but think that there was an alternative somewhere...

There’s a different between intuitive and learned responses. Getting back a known card rather than a random card from a graveyard is a learned response. When I make changes (and remember that Magic is a game about change) I tend to be much more willing to overwrite learned responses to intuitive responses because people can learn to do things differently but it’s a lot harder to make things feel right differently. Having played with the random graveyard retrieval, I found it to be a fun change of pace. It also created more tension, which I feel works well in a horror set. Note that this isn’t a permanent change but something we’re doing for Innistrad.
