Gatherer Card Rulings [Nov 2009]

• 9/25/2006: When damage is dealt to Phyrexian Totem, its triggered ability will trigger. A number of permanents equal to the amount of damage dealt will be sacrificed when the ability resolves. It doesn't matter if Phyrexian Totem isn't on the battlefield when the ability resolves, as long as Phyrexian Totem was a creature as it left the battlefield. If one of the permanents sacrificed is Phyrexian Totem itself, the requisite number of other permanents must still be sacrificed.
• 8/1/2008: A noncreature permanent that turns into a creature is subject to the "summoning sickness" rule: It can only attack, and its {T} abilities can only be activated, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
