This recently came up in a casual game at the store I'm judging at.
Nathan controls a
Kozilek, Butcher of Truth enchanted with
Darksteel Mutation. During combat, he blocks Anna's
Sedge Scorpion. Combat damage is dealt. In her second main phase, Anna casts
Disenchant on the Mutation. The players can't agree if Kozilek is getting destroyed or not. I am called at this point.
The question basically boils down to “does deathtouch check more than once if it destroys the creature affected by it” - I ruled that due to the wording of 702.2c deathtouch only checks during the
next time SBAs are checked, so the Kozilek would still be in play.
Is this correct?
