2 rulings from Wizards of the Coast
- 1 May 2006A permanent with the subtype Demon, including Rakdos the Defiler itself, can't be sacrificed this way.
- 1 May 2006To calculate the number of permanents that must be sacrificed, count the number of permanents the affected player controls that don't have the subtype Demon, then divide that number in half and round up. For example, a player who controls eleven non-Demon permanents will need to sacrifice six of them.
