3 rulings from Wizards of the Coast
- 1 October 2009A token creature that’s destroyed is put into its owner’s graveyard, and will be counted by Hellfire’s effect. (Immediately after Hellfire finishes resolving, the token will cease to exist.)
- 1 October 2009Hellfire checks the number of creatures put into graveyards as the result of its effect, not the number of creatures destroyed as a result of its effect. For example, a replacement effect that says “If a creature would be put into a graveyard from the battlefield, exile it instead” won’t affect whether a creature is destroyed or not, but will affect whether it’s put into a graveyard or not.
- 1 October 2009A creature that regenerates instead of being destroyed doesn’t leave the battlefield, so it’s not put into a graveyard.
