Magic: The Gathering Oracle Changes
When cards from a new Magic: The Gathering set are added to the Oracle card reference, several older cards are also issued errata. For years, these changes weren't officially detailed, so I've compiled Oracle changes from set to set since the update from Ninth Edition to Ravnica: City of Guilds. Starting with Tenth Edition, Magic rules manager Mark Gottlieb has written update bulletins for the official Magic web site explaining these changes, which are also linked below.
